# NAME

routerSendUnsolRaDefault - verify a host sending valid RSs

# TARGET

      Router Only

# SYNOPSIS

      routerSendUnsolRaDefault.seq [-tooloption ...] -p routerSendUnsolRaDefault.def

# INITIALIZATION

Start NUT advertising RAs whose parameters are as same as those.

# TEST PROCEDURE

routerSendUnsolRaDefault verifies that a NUT send valid RSs by the rules.

      - A host sends valid RSs whose interval is
        MAX_INITIAL_RTR_ADVERT_INTERVAL(16 sec).

      - A host sends the RSs at the most
        MAX_INITIAL_RTR_ADVERTISEMENTS (3) times.

# JUDGMENT

      1. NUT throw valid RAs:
         - whose parameter are as same as those.
         - that may contain a source link-layer option.
         - that may contain a MTU option.
         - that may contain a Prefix option.

      2. The interval between RAs is MAX_INITIAL_RTR_ADVERT_INTERVAL(16 sec).
         Because MinRtrAdvInterval(600*0.33 sec) is greater than
         MAX_INITIAL_RTR_ADVERT_INTERVAL(16 sec).

      3. NUT throws the RAs at the most MAX_INITIAL_RTR_ADVERTISEMENTS (3) times.

# TERMINATION

      N/A

# NOTE

      TBD

# REFERENCE

    6.2.4.  Sending Unsolicited Router Advertisements

       For the first few advertisements (up to
       MAX_INITIAL_RTR_ADVERTISEMENTS) sent from an interface when it
       becomes an advertising interface, if the randomly chosen interval is
       greater than MAX_INITIAL_RTR_ADVERT_INTERVAL, the timer SHOULD be set
       to MAX_INITIAL_RTR_ADVERT_INTERVAL instead.  Using a smaller interval
       for the initial advertisements increases the likelihood of a router
       being discovered quickly when it first becomes available, in the
       presence of possible packet loss.
