Overview
********

Zebra is a routing software package that provides TCP/IP based routing
services with routing protocols support such as RIPv1, RIPv2, RIPng,
OSPFv2, OSPFv3, BGP-4, and BGP-4+ (*note Supported RFC::).  Zebra also
supports special BGP Route Reflector and Route Server behavior.  In
addition to traditional IPv4 routing protocols, Zebra also supports
IPv6 routing protocols.  With SNMP daemon which supports SMUX protocol,
Zebra provides routing protocol MIBs (*note SNMP Support::).

   Zebra uses an advanced software architecture to provide you with a
high quality, multi server routing engine.  Zebra has an interactive
user interface for each routing protocol and supports common client
commands.  Due to this design, you can add new protocol daemons to Zebra
easily.  You can use Zebra library as your program's client user
interface.

   Zebra is an official GNU software and distributed under the GNU
General Public License.

About Zebra
===========

Today, TCP/IP networks are covering all of the world.  The Internet has
been deployed in many countries, companies, and to the home.  When you
connect to the Internet your packet will pass many routers which have
TCP/IP routing functionality.

   A system with Zebra installed acts as a dedicated router.  With
Zebra, your machine exchanges routing information with other routers
using routing protocols.  Zebra uses this information to update the
kernel routing table so that the right data goes to the right place.
You can dynamically change the configuration and you may view routing
table information from the Zebra terminal interface.

   Adding to routing protocol support, Zebra can setup interface's
flags, interface's address, static routes and so on.  If you have a
small network, or a stub network, or xDSL connection, configuring the
Zebra routing software is very easy.  The only thing you have to do is
to set up the interfaces and put a few commands about static routes
and/or default routes.  If the network is rather large, or if the
network structure changes frequently, you will want to take advantage
of Zebra's dynamic routing protocol support for protocols such as RIP,
OSPF or BGP.  Zebra is with you.

   Traditionally, UNIX based router configuration is done by `ifconfig'
and `route' commands.  Status of routing table is displayed by
`netstat' utility.  Almost of these commands work only if the user has
root privileges.  Zebra has a different system administration method.
There are two user modes in Zebra.  One is normal mode, the other is
enable mode.  Normal mode user can only view system status, enable mode
user can change system configuration.  This UNIX account independent
feature will be great help to the router administrator.

   Currently, Zebra supports common unicast routing protocols.
Multicast routing protocols such as BGMP, PIM-SM, PIM-DM will be
supported in Zebra 2.0.  MPLS support is going on.  In the future,
TCP/IP filtering control, QoS control, diffserv configuration will be
added to Zebra.  Zebra project's final goal is making a productive,
quality free TCP/IP routing software.


File: zebra.info,  Node: System Architecture,  Next: Supported Platforms,  Prev: About Zebra,  Up: Overview

System Architecture
===================

Traditional routing software is made as a one process program which
provides all of the routing protocol functionalities.  Zebra takes a
different approach.  It is made from a collection of several daemons
that work together to build the routing table.  There may be several
protocol-specific routing daemons and zebra the kernel routing manager.

   The `ripd' daemon handles the RIP protocol, while `ospfd' is a
daemon which supports OSPF version 2.  `bgpd' supports the BGP-4
protocol.  For changing the kernel routing table and for redistribution
of routes between different routing protocols, there is a kernel
routing table manager `zebra' daemon.  It is easy to add a new routing
protocol daemons to the entire routing system without affecting any
other software.  You need to run only the protocol daemon associated
with routing protocols in use.  Thus, user may run a specific daemon
and send routing reports to a central routing console.

   There is no need for these daemons to be running on the same machine.
You can even run several same protocol daemons on the same machine.
This architecture creates new possibilities for the routing system.

     +----+  +----+  +-----+  +-----+
     |bgpd|  |ripd|  |ospfd|  |zebra|
     +----+  +----+  +-----+  +-----+

     |  UNIX Kernel  routing table  |
     |                              |
     +------------------------------+
     
         Zebra System Architecture

   Multi-process architecture brings extensibility, modularity and
maintainability.  At the same time it also brings many configuration
files and terminal interfaces.  Each daemon has it's own configuration
file and terminal interface.  When you configure a static route, it must
be done in `zebra' configuration file.  When you configure BGP network
it must be done in `bgpd' configuration file.  This can be a very
annoying thing.  To resolve the problem, Zebra provides integrated user
interface shell called `vtysh'.  `vtysh' connects to each daemon with
UNIX domain socket and then works as a proxy for user input.

   Zebra was planned to use multi-threaded mechanism when it runs with a
kernel that supports multi-threads.  But at the moment, the thread
library which comes with GNU/Linux or FreeBSD has some problems with
running reliable services such as routing software, so we don't use
threads at all.  Instead we use the `select(2)' system call for
multiplexing the events.

   When `zebra' runs under a GNU Hurd kernel it will act as a kernel
routing table itself.  Under GNU Hurd, all TCP/IP services are provided
by user processes called `pfinet'.  Zebra will provide all the routing
selection mechanisms for the process.  This feature will be implemented
when GNU Hurd becomes stable.

Installation
************

There are three steps for installing the software: configuration,
compilation, and installation.

* Menu:

* Configure the Software::
* Build the Software::
* Install the Software::

   The easiest way to get Zebra running is to issue the following
commands:

     % configure
     % make
     % make install


File: zebra.info,  Node: Configure the Software,  Next: Build the Software,  Prev: Installation,  Up: Installation

Configure the Software
======================

Zebra has an excellent configure script which automatically detects
most host configurations.  There are several additional configure
options you can use to turn off IPv6 support, to disable the
compilation of specific daemons, and to enable SNMP support.

`--enable-guile'
     Turn on compilation of the zebra-guile interpreter.  You will need
     the guile library to make this.  zebra-guile implementation is not
     yet finished.  So this option is only useful for zebra-guile
     developers.

`--disable-ipv6'
     Turn off IPv6 related features and daemons.  Zebra configure script
     automatically detects IPv6 stack.  But sometimes you might want to
     disable IPv6 support of Zebra.

`--disable-zebra'
     Do not build zebra daemon.

`--disable-ripd'
     Do not build ripd.

`--disable-ripngd'
     Do not build ripngd.

`--disable-ospfd'
     Do not build ospfd.

`--disable-ospf6d'
     Do not build ospf6d.

`--disable-bgpd'
     Do not build bgpd.

`--disable-bgp-announce'
     Make `bgpd' which does not make bgp announcements at all.  This
     feature is good for using `bgpd' as a BGP announcement listener.

`--enable-netlink'
     Force to enable GNU/Linux netlink interface.  Zebra configure
     script detects netlink interface by checking a header file.  When
     the header file does not match to the current running kernel,
     configure script will not turn on netlink support.

`--enable-snmp'
     Enable SNMP support.  By default, SNMP support is disabled.

   You may specify any combination of the above options to the configure
script.  By default, the executables are placed in `/usr/local/sbin'
and the configuration files in `/usr/local/etc'. The `/usr/local/'
installation prefix and other directories may be changed using the
following options to the configuration script.

`--prefix=PREFIX'
     Install architecture-independent files in PREFIX [/usr/local].

`--sysconfdir=DIR'
     Read-only sample configuration file in DIR [PREFIX/etc].

     % ./configure --disable-ipv6

   This command will configure zebra and the routing daemons.

   There are several options available only to GNU/Linux systems: (1).

   ---------- Footnotes ----------

   (1) GNU/Linux has very flexible kernel configuration features.  If
you use GNU/Linux, make sure that the current kernel configuration is
what you want.  Zebra will run with any kernel configuration but some
recommendations do exist.

CONFIG_NETLINK
     Kernel/User netlink socket.  This is a brand new feature which
     enables an advanced interface between the Linux kernel and Zebra
     (*note Kernel Interface::).

CONFIG_RTNETLINK
     Routing messages.  This makes it possible to receive netlink
     routing messages.  If you specify this option, `zebra' can detect
     routing information updates directly from the kernel (*note Kernel
     Interface::).

CONFIG_IP_MULTICAST
     IP: multicasting.  This option should be specified when you use
     `ripd' or `ospfd' because these protocols use multicast.


   IPv6 support has been added in GNU/Linux kernel version 2.2.  If you
try to use the Zebra IPv6 feature on a GNU/Linux kernel, please make
sure the following libraries have been installed.  Please note that
these libraries will not be needed when you uses GNU C library 2.1 or
upper.

`inet6-apps'
     The `inet6-apps' package includes basic IPv6 related libraries such
     as `inet_ntop' and `inet_pton'.  Some basic IPv6 programs such as
     `ping', `ftp', and `inetd' are also included. The `inet-apps' can
     be found at <ftp://ftp.inner.net/pub/ipv6/>.

`net-tools'
     The `net-tools' package provides an IPv6 enabled interface and
     routing utility.  It contains `ifconfig', `route', `netstat', and
     other tools.  `net-tools' may be found at
     <http://www.tazenda.demon.co.uk/phil/net-tools/>.

Build the Software
==================

After configuring the software, you will need to compile it for your
system. Simply issue the command `make' in the root of the source
directory and the software will be compiled. If you have *any* problems
at this stage, be certain to send a bug report *Note Bug Reports::.

     % ./configure
     .
     .
     .
     ./configure output
     .
     .
     .
     % make


File: zebra.info,  Node: Install the Software,  Prev: Build the Software,  Up: Installation

Install the Software
====================

Installing the software to your system consists of copying the compiled
programs and supporting files to a standard location. After the
installation process has completed, these files have been copied from
your work directory to `/usr/local/bin', and `/usr/local/etc'.

   To install the Zebra suite, issue the following command at your shell
prompt: `make install'.

     %
     % make install
     %

   Zebra daemons have their own terminal interface or VTY.  After
installation, you have to setup each beast's port number to connect to
them.  Please add the following entries to `/etc/services'.

     zebrasrv      2600/tcp		  # zebra service
     zebra         2601/tcp		  # zebra vty
     ripd          2602/tcp		  # RIPd vty
     ripngd        2603/tcp		  # RIPngd vty
     ospfd         2604/tcp		  # OSPFd vty
     bgpd          2605/tcp		  # BGPd vty
     ospf6d        2606/tcp		  # OSPF6d vty

   If you use a FreeBSD newer than 2.2.8, the above entries are already
added to `/etc/services' so there is no need to add it. If you specify
a port number when starting the daemon, these entries may not be needed.

   You may need to make changes to the config files in
`/usr/local/etc/*.conf'. *Note Config Commands::.


File: zebra.info,  Node: Basic commands,  Next: Zebra,  Prev: Installation,  Up: Top

Basic commands
**************

There are five routing daemons in use, and there is one manager daemon.
These daemons may be located on separate machines from the manager
daemon.  Each of these daemons will listen on a particular port for
incoming VTY connections.  The routing daemons are:

   * `ripd', `ripngd', `ospfd', `ospf6d', `bgpd'

   * `zebra'

   The following sections discuss commands common to all the routing
daemons.

* Menu:

* Config Commands::             Commands used in config files
* Common Invocation Options::   Starting the daemons
* Virtual Terminal Interfaces::  Interacting with the daemons


File: zebra.info,  Node: Config Commands,  Next: Common Invocation Options,  Prev: Basic commands,  Up: Basic commands

Config Commands
===============

* Menu:

* Basic Config Commands::       Some of the generic config commands
* Sample Config File::          An example config file

   In a config file, you can write the debugging options, a vty's
password, routing daemon configurations, a log file name, and so forth.
This information forms the initial command set for a routing beast as
it is starting.

   Config files are generally found in:

     `/usr/local/etc/*.conf'

   Each of the daemons has its own config file.  For example, zebra's
default config file name is:

     `/usr/local/etc/zebra.conf'

   The daemon name plus `.conf' is the default config file name. You
can specify a config file using the `-f' or `--config-file' options
when starting the daemon.

Sample Config File
------------------

Below is a sample configuration file for the zebra daemon.

     !
     ! Zebra configuration file
     !
     hostname Router
     password zebra
     enable password zebra
     !
     log stdout
     !
     !

   '!' and '#' are comment characters.  If the first character of the
word is one of the comment characters then from the rest of the line
forward will be ignored as a comment.

     password zebra!password

   If a comment character is not the first character of the word, it's a
normal character. So in the above example '!' will not be regarded as a
comment and the password is set to 'zebra!password'.


File: zebra.info,  Node: Common Invocation Options,  Next: Virtual Terminal Interfaces,  Prev: Config Commands,  Up: Basic commands

Common Invocation Options
=========================

These options apply to all Zebra daemons.

`-d'
`--daemon'
     Runs in daemon mode.

`-f FILE'
`--config_file=FILE'
     Set configuration file name.

`-h'
`--help'
     Display this help and exit.

`-i FILE'
`--pid_file=FILE'
     Upon startup the process identifier of the daemon is written to a
     file, typically in `/var/run'.  This file can be used by the init
     system to implement commands such as `.../init.d/zebra status',
     `.../init.d/zebra restart' or `.../init.d/zebra stop'.

     The file name is an run-time option rather than a configure-time
     option so that multiple routing daemons can be run simultaneously.
     This is useful when using Zebra to implement a routing looking
     glass.  One machine can be used to collect differing routing views
     from differing points in the network.

`-P PORT'
`--vty_port=PORT'
     Set the VTY port number.

`-v'
`--version'
     Print program version.

Static Route Commands
=====================

Static routing is a very fundamental feature of routing technology.  It
defines static prefix and gateway.

 - Command: ip route NETWORK GATEWAY
     NETWORK is destination prefix with format of A.B.C.D/M.  GATEWAY
     is gateway for the prefix.  When GATEWAY is A.B.C.D format.  It is
     taken as a IPv4 address gateway.  Otherwise it is treated as an
     interface name.

          ip route 10.0.0.0/8 10.0.0.2
          ip route 10.0.0.0/8 ppp0

     First example defines 10.0.0.0/8 static route with gateway
     10.0.0.2.  Second one defines the same prefix but with gateway to
     interface ppp0.

 - Command: ip route NETWORK NETMASK GATEWAY
     This is alternate version of above command.  When NETWORK is
     A.B.C.D format, user must define NETMASK value with A.B.C.D
     format.  GATEWAY is same option as above command

          ip route 10.0.0.0 255.255.255.0 10.0.0.2
          ip route 10.0.0.0 255.255.255.0 ppp0

     This is a same setting using this statement.

 - Command: ip route NETWORK GATEWAY DISTANCE

   Multiple nexthop static route

     ip route 10.0.0.1/32 10.0.0.2
     ip route 10.0.0.1/32 10.0.0.3
     ip route 10.0.0.1/32 eth0

   If there is no route to 10.0.0.2 and 10.0.0.3, and interface eth0 is
reachable, then the last route is installed into the kernel.

     zebra> show ip route
     S>  10.0.0.1/32 [1/0] via 10.0.0.2 inactive
                           via 10.0.0.3 inactive
       *                   is directly connected, eth0

   Floating static route

 - Command: ipv6 route NETWORK GATEWAY

 - Command: ipv6 route NETWORK GATEWAY DISTANCE

 - Command: table TABLENO
     Select the primary kernel routing table to be used.  This only
     works for kernels supporting multiple routing tables (like
     GNU/Linux 2.2.x and later).  After setting TABLENO with this
     command, static routes defined after this are added to the
     specified table.

          C* 203.181.89.240/28      eth0

 - Command: show ipv6 route

 - Command: show interface

 - Command: show ipforward
     Display whether the host's IP forwarding function is enabled or
     not.  Almost any UNIX kernel can be configured with IP forwarding
     disabled.  If so, the box can't work as a router.

 - Command: show ipv6forward
     Display whether the host's IP v6 forwarding is enabled or not.

RIP
***

RIP - Routing Information Protocol is widely deployed interior gateway
protocol.  RIP was developed in the 1970s at Xerox Labs as part of the
XNS routing protocol.  RIP is a "distance-vector" protocol and is based
on the "Bellman-Ford" algorithms.  As a distance-vector protocol, RIP
router send updates to its neighbors periodically, thus allowing the
convergence to a known topology.  In each update, the distance to any
given network will be broadcasted to its neighboring router.

   `ripd' supports RIP version 2 as described in RFC2453 and RIP
version 1 as described in RFC1058.

File: zebra.info,  Node: Starting and Stopping ripd,  Next: RIP Configuration,  Prev: RIP,  Up: RIP

Starting and Stopping ripd
==========================

The default configuration file name of `ripd''s is `ripd.conf'.  When
invocation `ripd' searches directory /usr/local/etc.  If `ripd.conf' is
not there next search current directory.

   RIP uses UDP port 521 to send and receive RIP packets.  So the user
must have the capability to bind the port, generally this means that
the user must have superuser privileges.  RIP protocol requires
interface information maintained by `zebra' daemon.  So running `zebra'
is mandatory to run `ripd'.  Thus minimum sequence for running RIP is
like below:

     # zebra -d
     # ripd -d

   Please note that `zebra' must be invoked before `ripd'.

   To stop `ripd'.  Please use `kill `cat /var/run/ripd.pid`'.  Certain
signals have special meaningss to `ripd'.

`SIGHUP'
     Reload configuration file `ripd.conf'.  All configurations are
     reseted.  All routes learned so far are cleared and removed from
     routing table.

`SIGUSR1'
     Rotate `ripd' logfile.

`SIGINT'
`SIGTERM'
     `ripd' sweeps all installed RIP routes then terminates properly.

   `ripd' invocation options.  Common options that can be specified
(*note Common Invocation Options::).

`-r'
`--retain'
     When the program terminates, retain routes added by `ripd'.

* Menu:

* RIP netmask::


File: zebra.info,  Node: RIP netmask,  Prev: Starting and Stopping ripd,  Up: Starting and Stopping ripd

RIP netmask
-----------

The netmask features of `ripd' support both version 1 and version 2 of
RIP.  Version 1 of RIP originally contained no netmask information.  In
RIP version 1, network classes were originally used to determine the
size of the netmask.  Class A networks use 8 bits of mask, Class B
networks use 16 bits of masks, while Class C networks use 24 bits of
mask.  Today, the most widely used method of a network mask is assigned
to the packet on the basis of the interface that received the packet.
Version 2 of RIP supports a variable length subnet mask (VLSM).  By
extending the subnet mask, the mask can be divided and reused.  Each
subnet can be used for different purposes such as large to middle size
LANs and WAN links.  Zebra `ripd' does not support the non-sequential
netmasks that are included in RIP Version 2.

   In a case of similar information with the same prefix and metric, the
old information will be suppressed.  Ripd does not currently support
equal cost multipath routing.


File: zebra.info,  Node: RIP Configuration,  Next: How to Announce RIP route,  Prev: Starting and Stopping ripd,  Up: RIP

RIP Configuration
=================

 - Command: router rip
     The `router rip' command is necessary to enable RIP.  To disable
     RIP, use the `no router rip' command.  RIP must be enabled before
     carrying out any of the RIP commands.

 - Command: no rouer rip
     Disable RIP.

   RIP can be configured to process either Version 1 or Version 2
packets, the default mode is Version 2.  If no version is specified,
then the RIP daemon will default to Version 2.  If RIP is set to Version
1, the setting "Version 1" will be displayed, but the setting "Version
2" will not be displayed whether or not Version 2 is set explicitly as
the version of RIP being used.

 - RIP Command: network NETWORK
 - RIP Command: no network NETWORK
     Set the RIP enable interface by NETWORK.  The interfaces which
     have addresses matching with NETWORK are enabled.

     This group of commands either enables or disables RIP interfaces
     between certain numbers of a specified network address.  For
     example, if the network for 10.0.0.0/24 is RIP enabled, this would
     result in all the addresses from 10.0.0.0 to 10.0.0.255 being
     enabled for RIP.  The `no network' command will disable RIP for
     the specified network.

 - RIP Command: network IFNAME
 - RIP Command: no network IFNAME
     Set a RIP enabled interface by IFNAME.  Both the sending and
     receiving of RIP packets will be enabled on the port specified in
     the `network ifname' command.  The `no network ifname' command
     will disable RIP on the specified interface.

 - RIP Command: neighbor A.B.C.D
 - RIP Command: no neighbor A.B.C.D
     Specify RIP neighbor.  When a neighbor doesn't understand
     multicast, this command is used to specify neighbors.  In some
     cases, not all routers will be able to understand multicasting,
     where packets are sent to a network or a group of addresses.  In a
     situation where a neighbor cannot process multicast packets, it is
     necessary to establish a direct link between routers.  The
     neighbor command allows the network administrator to specify a
     router as a RIP neighbor.  The `no neighbor a.b.c.d' command will
     disable the RIP neighbor.

   Below is very simple RIP configuration.  Interface `eth0' and
interface which address match to `10.0.0.0/8' are RIP enabled.

     !
     router rip
      network 10.0.0.0/8
      network eth0
     !

   Passive interface

 - RIP command: passive-interface IFNAME
 - RIP command: no passive-interface IFNAME
     This command sets the specified interface to passive mode.  On
     passive mode interface, all receiving packets are processed as
     normal and ripd does not send either multicast or unicast RIP
     packets except to RIP neighbors specified with `neighbor' command.

   RIP version handling

 - RIP Command: version VERSION
     Set RIP process's version.  VERSION can be "1" or "2".

 - Interface command: ip rip send version VERSION
     VERSION can be `1', `2', `1 2'.  This configuration command
     overrides the router's rip version setting.  The command will
     enable the selected interface to send packets with RIP Version 1,
     RIP Version 2, or both.  In the case of '1 2', packets will be
     both broadcast and multicast.

 - Interface command: ip rip receive version VERSION
     Version setting for incoming RIP packets.  This command will
     enable the selected interface to receive packets in RIP Version 1,
     RIP Version 2, or both.

   RIP split-horizon

 - Interface command: ip split-horizon
 - Interface command: no ip split-horizon
     Control split-horizon on the interface.  Default is `ip
     split-horizon'.  If you don't perform split-horizon on the
     interface, please specify `no ip split-horizon'.

How to Announce RIP route
=========================

 - RIP command: redistribute kernel
 - RIP command: redistribute kernel metric <0-16>
 - RIP command: redistribute kernel route-map ROUTE-MAP
 - RIP command: no redistribute kernel
     `redistribute kernel' redistributes routing information from
     kernel route entries into the RIP tables. `no redistribute kernel'
     disables the routes.

 - RIP command: redistribute static
 - RIP command: redistribute static metric <0-16>
 - RIP command: redistribute static route-map ROUTE-MAP
 - RIP command: no redistribute static
     `redistribute static' redistributes routing information from
     static route entries into the RIP tables. `no redistribute static'
     disables the routes.

 - RIP command: redistribute connected
 - RIP command: redistribute connected metric <0-16>
 - RIP command: redistribute connected route-map ROUTE-MAP
 - RIP command: no redistribute connected
     Redistribute connected routes into the RIP tables.  `no
     redistribute connected' disables the connected routes in the RIP
     tables.  This command redistribute connected of the interface
     which RIP disabled.  The connected route on RIP enabled interface
     is announced by default.

 - RIP command: redistribute ospf
 - RIP command: redistribute ospf metric <0-16>
 - RIP command: redistribute ospf route-map ROUTE-MAP
 - RIP command: no redistribute ospf
     `redistribute ospf' redistributes routing information from ospf
     route entries into the RIP tables. `no redistribute ospf' disables
     the routes.

 - RIP command: redistribute bgp
 - RIP command: redistribute bgp metric <0-16>
 - RIP command: redistribute bgp route-map ROUTE-MAP
 - RIP command: no redistribute bgp
     `redistribute bgp' redistributes routing information from bgp
     route entries into the RIP tables. `no redistribute bgp' disables
     the routes.

   If you want to specify RIP only static routes:

 - RIP command: default-information originate

 - RIP command: route A.B.C.D/M
 - RIP command: no route A.B.C.D/M
     This command is specific to Zebra.  The `route' command makes a
     static route only inside RIP. This command should be used only by
     advanced users who are particularly knowledgeable about the RIP
     protocol.  In most cases, we recommend creating a static route in
     Zebra and redistributing it in RIP using `redistribute static'.


File: zebra.info,  Node: Filtering RIP Routes,  Next: RIP Metric Manipulation,  Prev: How to Announce RIP route,  Up: RIP

Filtering RIP Routes
====================

RIP routes can be filtered by a distribute-list.

 - Command: distribute-list ACCESS_LIST DIRECT IFNAME
     You can apply access lists to the interface with a
     `distribute-list' command.  ACCESS_LIST is the access list name.
     DIRECT is `in' or `out'.  If DIRECT is `in' the access list is
     applied to input packets.

     The `distribute-list' command can be used to filter the RIP path.
     `distribute-list' can apply access-lists to a chosen interface.
     First, one should specify the access-list.  Next, the name of the
     access-list is used in the distribute-list command.  For example,
     in the following configuration `eth0' will permit only the paths
     that match the route 10.0.0.0/8

          !
          router rip
           distribute-list private in eth0
          !
          access-list private permit 10 10.0.0.0/8
          access-list private deny any
          !

   `distribute-list' can be applied to both incoming and outgoing data.

 - Command: distribute-list prefix PREFIX_LIST (in|out) IFNAME
     You can apply prefix lists to the interface with a
     `distribute-list' command.  PREFIX_LIST is the prefix list name.
     Next is the direction of `in' or `out'.  If DIRECT is `in' the
     access list is applied to input packets.


File: zebra.info,  Node: RIP Metric Manipulation,  Next: RIP distance,  Prev: Filtering RIP Routes,  Up: RIP

RIP Metric Manipulation
=======================

RIP metric is a value for distance for the network.  Usually `ripd'
increment the metric when the network information is received.
Redistributed routes' metric is set to 1.

 - RIP command: default-metric <1-16>
 - RIP command: no default-metric <1-16>
     This command modifies the default metric value for redistributed
     routes.  The default value is 1.  This command does not affect
     connected route even if it is redistributed by `redistribute
     connected'.  To modify connected route's metric value, please use
     `redistribute connected metric' or `route-map'.  `offset-list' also
     affects connected routes.

 - RIP command: offset-list ACCESS-LIST (in|out)
 - RIP command: offset-list ACCESS-LIST (in|out) IFNAME


File: zebra.info,  Node: RIP distance,  Next: RIP route-map,  Prev: RIP Metric Manipulation,  Up: RIP

RIP distance
============

Distance value is used in zebra daemon.  Default RIP distance is 120.

 - RIP command: distance <1-255>
 - RIP command: no distance <1-255>
     Set default RIP distance to specified value.

 - RIP command: distance <1-255> A.B.C.D/M
 - RIP command: no distance <1-255> A.B.C.D/M
     Set default RIP distance to specified value when the route's
     source IP address matches the specified prefix.

 - RIP command: distance <1-255> A.B.C.D/M ACCESS-LIST
 - RIP command: no distance <1-255> A.B.C.D/M ACCESS-LIST
     Set default RIP distance to specified value when the route's
     source IP address matches the specified prefix and the specified
     access-list.

RIP route-map
=============

Usage of `ripd''s route-map support.

   Optional argument route-map MAP_NAME can be added to each
`redistribute' statement.

     redistribute static [route-map MAP_NAME]
     redistribute connected [route-map MAP_NAME]
     .....

   Cisco applies route-map _before_ routes will exported to rip route
table.  In current Zebra's test implementation, `ripd' applies route-map
after routes are listed in the route table and before routes will be
announced to an interface (something like output filter). I think it is
not so clear, but it is draft and it may be changed at future.

   Route-map statement (*note Route Map::) is needed to use route-map
functionality.

 - Route Map: match interface WORD
     This command match to incoming interface.  Notation of this match
     is different from Cisco. Cisco uses a list of interfaces - NAME1
     NAME2 ... NAMEN.  Ripd allows only one name (maybe will change in
     the future).  Next - Cisco means interface which includes next-hop
     of routes (it is somewhat similar to "ip next-hop" statement).
     Ripd means interface where this route will be sent. This
     difference is because "next-hop" of same routes which sends to
     different interfaces must be different. Maybe it'd be better to
     made new matches - say "match interface-out NAME" or something
     like that.

 - Route Map: match ip address WORD
 - Route Map: match ip address prefix-list WORD
     Match if route destination is permitted by access-list.

 - Route Map: match ip next-hop A.B.C.D
     Cisco uses here <access-list>, `ripd' IPv4 address. Match if route
     has this next-hop (meaning next-hop listed in the rip route table
     - "show ip rip")

 - Route Map: match metric <0-4294967295>
     This command match to the metric value of RIP updates.  For other
     protocol compatibility metric range is shown as <0-4294967295>.
     But for RIP protocol only the value range <0-16> make sense.

 - Route Map: set ip next-hop A.B.C.D
     This command set next hop value in RIPv2 protocol.  This command
     does not affect RIPv1 because there is no next hop field in the

RIP Timers
==========

 - RIP command: timers basic UPDATE TIMEOUT GARBAGE
     RIP protocol has several timers.  User can configure those timers'
     values by `timers basic' command.

     The default settings for the timers are as follows:

        * The update timer is 30 seconds. Every update timer seconds,
          the RIP process is awakened to send an unsolicited Response
          message containing the complete routing table to all
          neighboring RIP routers.

        * The timeout timer is 180 seconds. Upon expiration of the
          timeout, the route is no longer valid; however, it is
          retained in the routing table for a short time so that
          neighbors can be notified that the route has been dropped.

        * The garbage collect timer is 120 seconds.  Upon expiration of
          the garbage-collection timer, the route is finally removed
          from the routing table.


     The `timers basic' command allows the the default values of the
     timers listed above to be changed.

 - RIP command: no timers basic
     The `no timers basic' command will reset the timers to the default
     settings listed above.

OSPFv2
******

OSPF version 2 is a routing protocol which described in RFC2328 - `OSPF
Version 2'.  OSPF is IGP (Interior Gateway Protocols).  Compared with
RIP, OSPF can provide scalable network support and faster convergence
time.  OSPF is widely used in large networks such as ISP backbone and
enterprise networks.

File: zebra.info,  Node: Configuring ospfd,  Next: OSPF router,  Prev: OSPFv2,  Up: OSPFv2

Configuring ospfd
=================

There is no `ospfd' specific options.  Common options can be specified
(*note Common Invocation Options::) to `ospfd'.  `ospfd' needs
interface information from `zebra'.  So please make it sure `zebra' is
running before invoking `ospfd'.

   Like other daemons, `ospfd' configuration is done in OSPF specific
configuration file `ospfd.conf'.


File: zebra.info,  Node: OSPF router,  Next: OSPF area,  Prev: Configuring ospfd,  Up: OSPFv2

OSPF router
===========

To start OSPF process you have to specify the OSPF router.  As of this
writing, `ospfd' does not support multiple OSPF processes.

 - Command: router ospf
 - Command: no router ospf
     Enable or disable the OSPF process.  `ospfd' does not yet support
     multiple OSPF processes.  So you can not specify an OSPF process
     number.

 - OSPF Command: ospf router-id A.B.C.D
 - OSPF Command: no ospf router-id

 - OSPF Command: ospf abr-type TYPE
 - OSPF Command: no ospf abr-type TYPE
     TYPE can be cisco|ibm|shortcut|standard More information regarding
     the behaviour controlled by this command can be found in
     draft-ietf-ospf-abr-alt-05.txt.  Quote: "Though the definition of
     the Area Border Router (ABR) in the OSPF specification does not
     require a router with multiple attached areas to have a backbone
     connection, it is actually necessary to provide successful routing
     to the inter-area and external destinations. If this requirement
     is not met, all traffic destined for the areas not connected to
     such an ABR or out of the OSPF domain, is dropped.  This document
     describes alternative ABR behaviors implemented in Cisco and IBM
     routers."

 - OSPF Command: ospf rfc1583compatibility
 - OSPF Command: no ospf rfc1583compatibility
     This rfc2328, the sucessor to rfc1583, suggests according to
     section G.2 (changes) in section 16.4 a change to the path
     preference algorithm that prevents possible routing loops that
     were possible in the old version of OSPFv2. More specificly it
     demands that inter-area paths and intra-area path are now of equal
     preference but still both preferred to external paths.

bgpd's command must be configured in `bgpd.conf'.

   `bgpd' specific invocation options are described below.  Common
options may also be specified (*note Common Invocation Options::).

`-p PORT'
`--bgp_port=PORT'
     Set the bgp protocol's port number.

`-r'
`--retain'
     When program terminates, retain BGP routes added by zebra.

BGP router
==========

First of all you must configure BGP router with `router bgp' command.
To configure BGP router, you need AS number.  AS number is an
identification of autonomous system.  BGP protocol uses the AS number
for detecting whether the BGP connection is internal one or external
one.

 - Command: router bgp ASN
     Enable a BGP protocol process with the specified ASN.  After this
     statement you can input any `BGP Commands'.  You can not create
     different BGP process under different ASN without specifying
     `multiple-instance' (*note Multiple instance::).

 - Command: no router bgp ASN
     Destroy a BGP protocol process with the specified ASN.

 - BGP: bgp router-id A.B.C.D
     This command specifies the router-ID.  If `bgpd' connects to
     `zebra' it gets interface and address information.  In that case
     default router ID value is selected as the largest IP Address of
     the interfaces.  When `router zebra' is not enabled `bgpd' can't
     get interface information so `router-id' is set to 0.0.0.0.  So
     please set router-id by hand.

BGP Peer commands
-----------------

In a `router bgp' clause there are neighbor specific configurations
required.

 - BGP: neighbor PEER shutdown
 - BGP: no neighbor PEER shutdown
     Shutdown the peer.  We can delete the neighbor's configuration by
     `no neighbor PEER remote-as AS-NUMBER' but all configuration of
     the neighbor will be deleted.  When you want to preserve the
     configuration, but want to drop the BGP peer, use this syntax.

 - BGP: neighbor PEER ebgp-multihop
 - BGP: no neighbor PEER ebgp-multihop

 - BGP: neighbor PEER description ...
 - BGP: no neighbor PEER description ...
     Set description of the peer.

 - BGP: neighbor PEER version VERSION
     Set up the neighbor's BGP version.  VERSION can be 4, 4+ or 4-.
     BGP version 4 is the default value used for BGP peering.  BGP
     version 4+ means that the neighbor supports Multiprotocol
     Extensions for BGP-4.  BGP version 4- is similar but the neighbor
     speaks the old Internet-Draft revision 00's Multiprotocol
     Extensions for BGP-4.  Some routing software is still using this
     version.

 - BGP: neighbor PEER interface IFNAME
 - BGP: no neighbor PEER interface IFNAME
     When you connect to a BGP peer over an IPv6 link-local address,
     you have to specify the IFNAME of the interface used for the
     connection.

 - BGP: neighbor PEER next-hop-self
 - BGP: no neighbor PEER next-hop-self
     This command specifies an announced route's nexthop as being
     equivalent to the address of the bgp router.

 - BGP: neighbor PEER update-source
 - BGP: no neighbor PEER update-source

 - BGP: neighbor PEER default-originate
 - BGP: no neighbor PEER default-originate
     `bgpd''s default is to not announce the default route (0.0.0.0/0)
     even it is in routing table.  When you want to announce default
     routes to the peer, use this command.

Autonomous System
=================

AS (Autonomous System) is one of the essential element of BGP.  BGP is
a distance vector routing protocol.  AS framework provides distance
vector metric and loop detection to BGP.  `RFC1930' - `Guidelines for
creation, selection, and registration of an Autonomous System (AS)'
describes how to use AS.

   AS number is tow octet digita value.  So the value range is from 1
to 65535.  AS numbers 64512 through 65535 are defined as private AS
numbers.  Private AS numbers must not to be advertised in the global
Internet.

AS Path Regular Expression
--------------------------

AS path regular expression can be used for displaying BGP routes and AS
path access list.  AS path regular expression is based on `POSIX
1003.2' regular expressions.  Following description is just a subset of
`POSIX' regular expression.  User can use full `POSIX' regular
expression.  Adding to that special character '_' is added for AS path
regular expression.

`.'
     Matches any single character.

`*'
     Matches 0 or more occurrences of pattern.

`+'
     Matches 1 or more occurrences of pattern.

`?'
     Match 0 or 1 occurrences of pattern.

`^'
     Matches the beginning of the line.

`$'
     Matches the end of the line.

`_'
     Character `_' has special meanings in AS path regular expression.
     It matches to space and comma , and AS set delimiter { and } and AS
     confederation delimiter `(' and `)'.  And it also matches to the
     beginning of the line and the end of the line.  So `_' can be used
     for AS value boundaries match.  `show ip bgp regexp _7675_'
     matches to all of BGP routes which as AS number include 7675.

BGP Communities Attribute
=========================

BGP communities attribute is widely used for implementing policy
routing.  Network operators can manipulate BGP communities attribute
based on their network policy.  BGP communities attribute is defined in
`RFC1997' - `BGP Communities Attribute' and `RFC1998' - `An Application
of the BGP Community Attribute in Multi-home Routing'.  It is an
optional transitive attribute, therefore local policy can travel
through different autonomous system.

   Communities attribute is a set of communities values.  Each
communities value is 4 octet long.  The following format is used to
define communities value.

`AS:VAL'
     This format represents 4 octet communities value.  `AS' is high
     order 2 octet in digit format.  `VAL' is low order 2 octet in
     digit format.  This format is useful to define AS oriented policy
     value.  For example, `7675:80' can be used when AS 7675 wants to
     pass local policy value 80 to neighboring peer.

`internet'
     `internet' represents well-known communities value 0.

`no-export'
     `no-export' represents well-known communities value `NO_EXPORT'
     (0xFFFFFF01).  All routes carry this value must not be advertised
     to outside a BGP confederation boundary.  If neighboring BGP peer
     is part of BGP confederation, the peer is considered as inside a
     BGP confederation boundary, so the route will be announced to the
     peer.

`no-advertise'
     `no-advertise' represents well-known communities value
     `NO_ADVERTISE'
     (0xFFFFFF02).  All routes carry this value must not be advertise
     to other BGP peers.

`local-AS'
     `local-AS' represents well-known communities value
     `NO_EXPORT_SUBCONFED' (0xFFFFFF03).  All routes carry this value
     must not be advertised to external BGP peers.  Even if the
     neighboring router is part of confederation, it is considered as
     external BGP peer, so the route will not be announced to the peer.

   When BGP communities attribute is received, duplicated communities
value in the communities attribute is ignored and each communities
values are sorted in numerical order.

BGP Community Lists
-------------------

BGP community list is a user defined BGP communites attribute list.
BGP community list can be used for matching or manipulating BGP
communities attribute in updates.

   There are two types of community list.  One is standard community
list and another is expanded community list.  Standard community list
defines communities attribute.  Expanded community list defines
communities attribute string with regular expression.  Standard
community list is compiled into binary format when user define it.
Standard community list will be directly compared to BGP communities
attribute in BGP updates.  Therefore the comparison is faster than
expanded community list.

 - Command: ip community-list standard NAME {permit|deny} COMMUNITY
     This command defines a new standard community list.  COMMUNITY is
     communities value.  The COMMUNITY is compiled into community
     structure.  We can define multiple community list under same name.
     In that case match will happen user defined order.  Once the
     community list matches to communities attribute in BGP updates it
     return permit or deny by the community list definition.  When
     there is no matched entry, deny will be returned.  When COMMUNITY
     is empty it matches to any routes.

 - Command: ip community-list expanded NAME {permit|deny} LINE
     This command defines a new expanded community list.  LINE is a
     string expression of communities attribute.  LINE can include
     regular expression to match communities attribute in BGP updates.

 - Command: no ip community-list NAME
 - Command: no ip community-list standard NAME
 - Command: no ip community-list expanded NAME
     These commands delete community lists specified by NAME.  All of
     community lists shares a single name space.  So community lists
     can be removed simpley specifying community lists name.

 - Command: show ip community-list
 - Command: show ip community-list NAME
     This command display current community list information.  When
     NAME is specified the specified community list's information is
     shown.

          # show ip community-list
          Named Community standard list CLIST
              permit 7675:80 7675:100 no-export
              deny internet
          Named Community expanded list EXPAND
              permit :
          
          # show ip community-list CLIST
          Named Community standard list CLIST
              permit 7675:80 7675:100 no-export
              deny internet

Numbered BGP Community Lists
----------------------------

When number is used for BGP community list name, the number has special
meanings.  Community list number in the range from 1 and 99 is standard
community list.  Community list number in the range from 100 to 199 is
expanded community list.  These community lists are called as numbered
community lists.  On the other hand normal community lists is called as
named community lists.

 - Command: ip community-list <1-99> {permit|deny} COMMUNITY
     This command defines a new community list.  <1-99> is standard
     community list number.  Community list name within this range
     defines standard community list.  When COMMUNITY is empty it
     matches to any routes.

 - Command: ip community-list <100-199> {permit|deny} COMMUNITY
     This command defines a new community list.  <100-199> is expanded
     community list number.  Community list name within this range
     defines expanded community list.

 - Command: ip community-list NAME {permit|deny} COMMUNITY
     When community list type is not specifed, the community list type
     is automatically detected.  If COMMUNITY can be compiled into
     communities attribute, the community list is defined as a standard
     community list.  Otherwise it is defined as an expanded community
     list.  This feature is left for backward compability.  Use of this
     feature is not recommended.

BGP Community in Route Map
--------------------------

In Route Map (*note Route Map::), we can match or set BGP communities
attribute.  Using this feature network operator can implement their
network policy based on BGP communities attribute.

   Following commands can be used in Route Map.

 - Route Map: match community WORD
 - Route Map: match community WORD exact-match
     This command perform match to BGP updates using community list
     WORD.  When the one of BGP communities value match to the one of
     communities value in community list, it is match.  When
     `exact-match' keyword is spcified, match happen only when BGP
     updates have completely same communities value specified in the
     community list.

 - Route Map: set community none
 - Route Map: set community COMMUNITY
 - Route Map: set community COMMUNITY additive
     This command manipulate communities value in BGP updates.  When
     `none' is specified as communities value, it removes entire
     communities attribute from BGP updates.  When COMMUNITY is not
     `none', specified communities value is set to BGP updates.  If BGP
     updates already has BGP communities value, the existing BGP
     communities value is replaced with specified COMMUNITY value.
     When `additive' keyword is specified, COMMUNITY is appended to the
     existing communities value.

 - Route Map: set comm-list WORD delete
     This command remove communities value from BGP communities
     attribute.  The WORD is community list name.  When BGP route's
     communities value matches to the community list WORD, the
     communities value is removed.  When all of communities value is
     removed eventually, the BGP update's communities attribute is
     completely removed.

Display BGP Routes by Community
-------------------------------

To show BGP routes which has specific BGP communities attribute, `show

can be used for `show ip bgp' command.

 - Command: show ip bgp community
 - Command: show ip bgp community COMMUNITY
 - Command: show ip bgp community COMMUNITY exact-match
     `show ip bgp community' displays BGP routes which has communities
     attribute.  When COMMUNITY is specified, BGP routes that matches
     COMMUNITY value is displayed.  For this command, `internet'
     keyword can't be used for COMMUNITY value.  When `exact-match' is
     specified, it display only routes that have an exact match.

 - Command: show ip bgp community-list WORD
 - Command: show ip bgp community-list WORD exact-match
     This commands display BGP routes that matches community list WORD.
     When `exact-match' is specified, display only routes that have an
     exact match.

Using BGP Communities Attribute
-------------------------------

Following configuration is the most typical usage of BGP communities
attribute.  AS 7675 provides upstream Internet connection to AS 100.
When following configuration exists in AS 7675, AS 100 networks
operator can set local preference in AS 7675 network by setting BGP
communities attribute to the updates.

     router bgp 7675
      neighbor 192.168.0.1 remote-as 100
      neighbor 192.168.0.1 route-map RMAP in
     !
     ip community-list 70 permit 7675:70
     ip community-list 70 deny
     ip community-list 80 permit 7675:80
     ip community-list 80 deny
     ip community-list 90 permit 7675:90
     ip community-list 90 deny
     !
     route-map RMAP permit 10
      match community 70
      set local-preference 70
     !
     route-map RMAP permit 20
      match community 80
      set local-preference 80
     !
     route-map RMAP permit 30
      match community 90
      set local-preference 90

   Following configuration announce 10.0.0.0/8 from AS 100 to AS 7675.
The route has communities value 7675:80 so when above configuration
exists in AS 7675, announced route's local preference will be set to
value 80.

     router bgp 100
      network 10.0.0.0/8
      neighbor 192.168.0.2 remote-as 7675
      neighbor 192.168.0.2 route-map RMAP out
     !
     ip prefix-list PLIST permit 10.0.0.0/8
     !
     route-map RMAP permit 10
      match ip address prefix-list PLIST
      set community 7675:80

   Following configuration is an example of BGP route filtering using
communities attribute.  This configuration only permit BGP routes which
has BGP communities value 0:80 or 0:90.  Network operator can put
special internal communities value at BGP border router, then limit the
BGP routes announcement into the internal network.

     router bgp 7675
      neighbor 192.168.0.1 remote-as 100
      neighbor 192.168.0.1 route-map RMAP in
     !
     ip community-list 1 permit 0:80 0:90
     !
     route-map RMAP permit in
      match community 1

   Following exmaple filter BGP routes which has communities value 1:1.
When there is no match community-list returns deny.  To avoid filtering
all of routes, we need to define permit any at last.

     router bgp 7675
      neighbor 192.168.0.1 remote-as 100
      neighbor 192.168.0.1 route-map RMAP in
     !
     ip community-list standard FILTER deny 1:1
     ip community-list standard FILTER permit
     !
     route-map RMAP permit 10
      match community FILTER

   Communities value keyword `internet' has special meanings in
standard community lists.  In below example `internet' act as match
any.  It matches all of BGP routes even if the route does not have
communities attribute at all.  So community list `INTERNET' is same as
above example's `FILTER'.

     ip community-list standard INTERNET deny 1:1
     ip community-list standard INTERNET permit internet

   Following configuration is an example of communities value deletion.
With this configuration communities value 100:1 and 100:2 is removed
from BGP updates.  For communities value deletion, only `permit'
community-list is used.  `deny' community-list is ignored.

     router bgp 7675
      neighbor 192.168.0.1 remote-as 100
      neighbor 192.168.0.1 route-map RMAP in
     !
     ip community-list standard DEL permit 100:1 100:2
     !
     route-map RMAP permit 10
      set comm-list DEL delete

BGP Extended Communities Attribute
==================================

BGP extended communities attribute is introduced with MPLS VPN/BGP
technology.  MPLS VPN/BGP expands capability of network infrastructure
to provide VPN functionality.  At the same time it requires a new
framework for policy routing.  With BGP Extended Communities Attribute
we can use Route Target or Site of Origin for implementing network
policy for MPLS VPN/BGP.

   BGP Extended Communities Attribute is similar to BGP Communities
Attribute.  It is an optional transitive attribute.  BGP Extended
Communities Attribute can carry multiple Extended Community value.
Each Extended Community value is eight octet length.

   BGP Extended Communities Attribute provides an extended range
compared with BGP Communities Attribute.  Adding to that there is a
type field in each value to provides community space structure.

   There are two format to define Extended Community value.  One is AS
based format the other is IP address based format.

`AS:VAL'
     This is a format to define AS based Extended Community value.
     `AS' part is 2 octets Global Administrator subfield in Extended
     Community value.  `VAL' part is 4 octets Local Administrator
     subfield.  `7675:100' represents AS 7675 policy value 100.

`IP-Address:VAL'
     This is a format to define IP address based Extended Community
     value.  `IP-Address' part is 4 octets Global Administrator
     subfield.  `VAL' part is 2 octets Local Administrator subfield.
     `10.0.0.1:100' represents

BGP Extended Community Lists
----------------------------

Expanded Community Lists is a user defined BGP Expanded Community Lists.

 - Command: ip extcommunity-list standard NAME {permit|deny}
EXTCOMMUNITY
     This command defines a new standard extcommunity-list.
     EXTCOMMUNITY is extended communities value.  The EXTCOMMUNITY is
     compiled into extended community structure.  We can define
     multiple extcommunity-list under same name.  In that case match
     will happen user defined order.  Once the extcommunity-list
     matches to extended communities attribute in BGP updates it return
     permit or deny based upon the extcommunity-list definition.  When
     there is no matched entry, deny will be returned.  When
     EXTCOMMUNITY is empty it matches to any routes.

 - Command: ip extcommunity-list expanded NAME {permit|deny} LINE
     This command defines a new expanded extcommunity-list.  LINE is a
     string expression of extended communities attribute.  LINE can
     include regular expression to match extended communities attribute
     in BGP updates.

 - Command: no ip extcommunity-list NAME
 - Command: no ip extcommunity-list standard NAME
 - Command: no ip extcommunity-list expanded NAME
     These commands delete extended community lists specified by NAME.
     All of extended community lists shares a single name space.  So
     extended community lists can be removed simpley specifying the
     name.

 - Command: show ip extcommunity-list
 - Command: show ip extcommunity-list NAME
     This command display current extcommunity-list information.  When
     NAME is specified the community list's information is shown.

Capability Negotiation
======================

When adding IPv6 routing information exchange feature to BGP.  There
were some proposals.  IETF IDR working group finally take a proposal
called Multiprotocol Extension for BGP.  The specification is described
in RFC2283.  The protocol does not define new protocols.  It defines
new attributes to existing BGP.  When it is used exchanging IPv6
routing information it is called BGP-4+.  When it is used for
exchanging multicast routing information it is called MBGP.

   `bgpd' supports Multiprotocol Extension for BGP.  So if remote peer
supports the protocol, `bgpd' can exchange IPv6 and/or multicast routing
information.

   Traditional BGP does not have the feature to detect remote peer's
capability whether it can handle other than IPv4 unicast routes.  This
is a big problem using Multiprotocol Extension for BGP to operational
network.  `draft-ietf-idr-bgp4-cap-neg-04.txt' is proposing a feature
called Capability Negotiation.  `bgpd' use this Capability Negotiation
to detect remote peer's capabilities.  If the peer is only configured
as IPv4 unicast neighbor, `bgpd' does not send these Capability
Negotiation packets.

   By default, Zebra will bring up peering with minimal common
capability for the both sides.  For example, local router has unicast
and multicast capabilitie and remote router has unicast capability.  In
this case, the local router will establish the connection with unicast
only capability.  When there are no common capabilities, Zebra sends
Unsupported Capability error and then resets the connection.

   If you want to completely match capabilities with remote peer.
Please use `strict-capability-match' command.

 - BGP: neighbor PEER strict-capability-match
 - BGP: no neighbor PEER strict-capability-match
     Strictly compares remote capabilities and local capabilities.  If
     capabilities are different, send Unsupported Capability error then
     reset connection.

   You may want to disable sending Capability Negotiation OPEN message
optional parameter to the peer when remote peer does not implement
Capability Negotiation.  Please use `dont-capability-negotiate' command
to disable the feature.

 - BGP: neighbor PEER dont-capability-negotiate
 - BGP: no neighbor PEER dont-capability-negotiate
     Suppress sending Capability Negotiation as OPEN message optional
     parameter to the peer.  This command only affects the peer is
     configured other than IPv4 unicast configuration.

   When remote peer does not have capability negotiation feature, remote
peer will not send any capabilities at all.  In that case, bgp
configures the peer with configured capabilities.

   You may prefer locally configured capabilities more than the
negotiated capabilities even though remote peer sends capabilities.  If
the peer is configured by `override-capability', `bgpd' ignores received
capabilities then override negotiated capabilities with configured
values.

 - BGP: neighbor PEER override-capability
 - BGP: no neighbor PEER override-capability
     Override the result of Capability Negotiation with local
     configuration.  Ignore remote peer's capability value.

Route Server
============

At an Internet Exchange point, many ISPs are connected to each other by
external BGP peering.  Normally these external BGP connection are done
by `full mesh' method.  As with internal BGP full mesh formation, this
method has a scaling problem.

   This scaling problem is well known.  Route Server is a method to
resolve the problem.  Each ISP's BGP router only peers to Route Server.
Route Server serves as BGP information exchange to other BGP routers.
By applying this method, numbers of BGP connections is reduced from
O(n*(n-1)/2) to O(n).

   Unlike normal BGP router, Route Server must have several routing
tables for managing different routing policies for each BGP speaker.
We call the routing tables as different `view's.  `bgpd' can work as
normal BGP router or Route Server or both at the same time.

File: zebra.info,  Node: Multiple instance,  Next: BGP instance and view,  Prev: Route Server,  Up: Route Server

Multiple instance
-----------------

To enable multiple view function of `bgpd', you must turn on multiple
instance feature beforehand.

 - Command: bgp multiple-instance
     Enable BGP multiple instance feature.  After this feature is
     enabled, you can make multiple BGP instances or multiple BGP views.

 - Command: no bgp multiple-instance
     Disable BGP multiple instance feature.  You can not disable this
     feature when BGP multiple instances or views exist.

   When you want to make configuration more Cisco like one,

 - Command: bgp config-type cisco
     Cisco compatible BGP configuration output.

   When bgp config-type cisco is specified,

   "no synchronization" is displayed.  "no auto-summary" is desplayed.

   "network" and "aggregate-address" argument is displayed as "A.B.C.D
M.M.M.M"

   Zebra: network 10.0.0.0/8 Cisco: network 10.0.0.0

   Zebra: aggregate-address 192.168.0.0/24 Cisco: aggregate-address
192.168.0.0 255.255.255.0

   Community attribute handling is also different.  If there is no
configuration is specified community attribute and extended community
attribute are sent to neighbor.  When user manually disable the feature
community attribute is not sent to the neighbor.  In case of "bgp
config-type cisco" is specified, community attribute is not sent to the
neighbor by default.  To send community attribute user has to specify
"neighbor A.B.C.D send-community" command.

   !  router bgp 1  neighbor 10.0.0.1 remote-as 1  no neighbor 10.0.0.1
send-community !

   !  router bgp 1  neighbor 10.0.0.1 remote-as 1  neighbor 10.0.0.1
send-community !

 - Command: bgp config-type zebra
     Zebra style BGP configuration.  This is default.

BGP instance and view
---------------------

BGP instance is a normal BGP process.  The result of route selection
goes to the kernel routing table.  You can setup different AS at the
same time when BGP multiple instance feature is enabled.

 - Command: router bgp AS-NUMBER
     Make a new BGP instance.  You can use arbitrary word for the NAME.

     bgp multiple-instance
     !
     router bgp 1
      neighbor 10.0.0.1 remote-as 2
      neighbor 10.0.0.2 remote-as 3
     !
     router bgp 2
      neighbor 10.0.0.3 remote-as 4
      neighbor 10.0.0.4 remote-as 5

   BGP view is almost same as normal BGP process. The result of route
selection does not go to the kernel routing table.  BGP view is only
for exchanging BGP routing information.

 - Command: router bgp AS-NUMBER view NAME
     Make a new BGP view.  You can use arbitrary word for the NAME.
     This view's route selection result does not go to the kernel
     routing table.

   With this command, you can setup Route Server like below.

     bgp multiple-instance
     !
     router bgp 1 view 1
      neighbor 10.0.0.1 remote-as 2
      neighbor 10.0.0.2 remote-as 3
     !
     router bgp 2 view 2
      neighbor 10.0.0.3 remote-as 4
      neighbor 10.0.0.4 remote-as 5


File: zebra.info,  Node: Routing policy,  Next: Viewing the view,  Prev: BGP instance and view,  Up: Route Server

Routing policy
--------------

You can set different routing policy for a peer.  For example, you can
set different filter for a peer.

     bgp multiple-instance
     !
     router bgp 1 view 1
      neighbor 10.0.0.1 remote-as 2
      neighbor 10.0.0.1 distribute-list 1 in
     !
     router bgp 1 view 2
      neighbor 10.0.0.1 remote-as 2
      neighbor 10.0.0.1 distribute-list 2 in

   This means BGP update from a peer 10.0.0.1 goes to both BGP view 1
and view 2.  When the update is inserted into view 1, distribute-list 1
is applied.  On the other hand, when the update is inserted into view 2,
distribute-list 2 is applied.

VTY shell
*********

`vtysh' is integrated shell of Zebra software.

   To use vtysh please specify --enable-vtysh to configure script.  To
use PAM for authentication use --with-libpam option to configure script.

   vtysh only searches /usr/local/etc path for vtysh.conf which is the
vtysh configuration file.  Vtysh does not search current directory for
configuration file because the file includes user authentication
settings.

   Currently, vtysh.conf has only one command.

     !
     username foo nopassword
     !

   With this set, user foo does not need password authentication for
user vtysh.  With PAM vtysh uses PAM authentication mechanism.

   If vtysh is compiled without PAM authentication, every user can use
vtysh without authentication.

Filtering
*********

Zebra provides many very flexible filtering features.  Filtering is used
for both input and output of the routing information.  Once filtering is
defined, it can be applied in any direction.

* Menu:

* IP Access List::
* IP Prefix List::


File: zebra.info,  Node: IP Access List,  Next: IP Prefix List,  Prev: Filtering,  Up: Filtering

IP Access List
--------------

 - Command: access-list NAME permit IPV4-NETWORK
 - Command: access-list NAME deny IPV4-NETWORK

   Basic filtering is done by `access-list' as shown in the following
example.

     access-list filter deny 10.0.0.0/9
     access-list filter permit 10.0.0.0/8


File: zebra.info,  Node: IP Prefix List,  Prev: IP Access List,  Up: Filtering

IP Prefix List
--------------

`ip prefix-list' provides the most powerful prefix based filtering
mechanism.  In addition to `access-list' functionality, `ip
prefix-list' has prefix length range specification and sequential
number specification.  You can add or delete prefix based filters to
arbitrary points of prefix-list using sequential number specification.

   If no ip prefix-list is specified, it acts as permit.  If `ip
prefix-list' is defined, and no match is found, default deny is applied.

 - Command: ip prefix-list NAME (permit|deny) PREFIX [le LEN] [ge LEN]
 - Command: ip prefix-list NAME seq NUMBER (permit|deny) PREFIX [le
LEN] [ge LEN]
     You can create `ip prefix-list' using above commands.

    seq
          seq NUMBER can be set either automatically or manually.  In
          the case that sequential numbers are set manually, the user
          may pick any number less than 4294967295.  In the case that
          sequential number are set automatically, the sequential
          number will increase by a unit of five (5) per list.  If a
          list with no specified sequential number is created after a
          list with a specified sequential number, the list will
          automatically pick the next multiple of five (5) as the list
          number.  For example, if a list with number 2 already exists
          and a new list with no specified number is created, the next
          list will be numbered 5.  If lists 2 and 7 already exist and
          a new list with no specified number is created, the new list
          will be numbered 10.

    le
          `le' command specifies prefix length.  The prefix list will be
          applied if the prefix length is less than or equal to the le
          prefix length.

    ge
          `ge' command specifies prefix length.  The prefix list will be
          applied if the prefix length is greater than or equal to the
          ge prefix length.



   Less than or equal to prefix numbers and greater than or equal to
prefix numbers can be used together.  The order of the le and ge
commands does not matter.

   If a prefix list with a different sequential number but with the
exact same rules as a previous list is created, an error will result.
However, in the case that the sequential number and the rules are
exactly similar, no error will result.

   If a list with the same sequential number as a previous list is
created, the new list will overwrite the old list.

   Matching of IP Prefix is performed from the smaller sequential
number to the larger.  The matching will stop once any rule has been
applied.

   In the case of no le or ge command,

   Version 0.85: the matching rule will apply to all prefix lengths that
matched the prefix list.

   Version 0.86 or later: In the case of no le or ge command, the prefix
length must match exactly the length specified in the prefix list.

IPv6 Support
************

Zebra fully supports IPv6 routing.  As described so far, Zebra supports
RIPng, OSPFv3 and BGP-4+.  You can give IPv6 addresses to an interface
and configure static IPv6 routing information.  Zebra-IPv6 also provides
automatic address configuration via a feature called `address auto
configuration'.  To do it, the router must send router advertisement
messages to the all nodes that exist on the network.

Kernel Interface
****************

There are several different methods for reading kernel routing table
information, updating kernel routing tables, and for looking up
interfaces.

`ioctl'
     The `ioctl' method is a very traditional way for reading or writing
     kernel information.  `ioctl' can be used for looking up interfaces
     and for modifying interface addresses, flags, mtu settings and
     other types of information.  Also, `ioctl' can insert and delete
     kernel routing table entries.  It will soon be available on almost
     any platform which zebra supports, but it is a little bit ugly
     thus far, so if a better method is supported by the kernel, zebra
     will use that.

`sysctl'
     `sysctl' can lookup kernel information using MIB (Management
     Information Base) syntax.  Normally, it only provides a way of
     getting information from the kernel.  So one would usually want to
     change kernel information using another method such as `ioctl'.

`proc filesystem'
     `proc filesystem' provides an easy way of getting kernel
     information.

`routing socket'

`netlink'
     On recent Linux kernels (2.0.x and 2.2.x), there is a kernel/user
     communication support called `netlink'.  It makes asynchronous
     communication between kernel and Zebra possible, similar to a
     routing socket on BSD systems.

     Before you use this feature, be sure to select (in kernel
     configuration) the kernel/netlink support option 'Kernel/User
     network link driver' and 'Routing messages'.

     Today, the /dev/route special device file is obsolete.  Netlink
     communication is done by reading/writing over netlink socket.

     After the kernel configuration, please reconfigure and rebuild
     Zebra.  You can use netlink as a dynamic routing update channel
     between Zebra and the kernel.

SNMP Support
************

SNMP (Simple Network Managing Protocol) is widely implemented feature
for collecting network information from router and/or host.  Zebra
itself does not support SNMP agent functionality.  But conjuction with
SNMP agent, Zebra provides routing protocol MIBs.

   Zebra uses SMUX protocol (RFC1227) for making communication with SNMP
agent.  There are several SNMP agent which support SMUX.  We recommend
to use the latest `net-snmp' software.

How to get net-snmp
===================

net-snmp is a free software which distributed so called "as is" software
license.  Please check the license which comes with distribution of
`net-snmp'.  The authors of net-snmp are the University of California,
the University of California at Davis, and the Electrical Engineering
department at the University of California at Davis.

   You can get net-snmp from <http://www.net-snmp.org/>.

   To enable SMUX protocol support, please configure `net-snmp' like
below.

     % configure --with-mib-modules=smux

   After compile and install `net-snmp', you will need to configure
smuxpeer.  I'm now using configuration shown below.  This means SMUX
client connects to MIB 1.3.6.1.6.3.1 with password test.

     /usr/local/share/snmp/snmpd.conf

SMUX configuration
==================

To enable SNMP support of Zebra, you have to configure Zebra with
`--enable-snmp' (*note Configure the Software::).

Zebra Protocol
**************

Zebra Protocol is a protocol which is used between protocol daemon and
zebra.  Each protocol daemon sends selected routes to zebra daemon.
Then zebra manages which route is installed into the forwarding table.

   Zebra Protocol is a TCP-based protocol.  Below is common header of
Zebra Protocol.

     0                   1                   2                   3

     |           Length (2)          |   Command (1) |

   Length is total packet length including this header length.  So
minimum length is three.  Command is Zebra Protocol command.

Packet Binary Dump Format
*************************

Zebra can dump routing protocol packet into file with a binary format
(*note Dump BGP packets and table::).

   It seems to be better that we share the MRT's header format for
backward compatibility with MRT's dump logs. We should also define the
binary format excluding the header, because we must support both IP v4
and v6 addresses as socket addresses and / or routing entries.

   In the last meeting, we discussed to have a version field in the
header. But Masaki told us that we can define new `type' value rather
than having a `version' field, and it seems to be better because we
don't need to change header format.

   Here is the common header format. This is same as that of MRT.

     0                   1                   2                   3
