# NAME

            To_Multi_Time_Exc.seq - check Message Processing Rules (ICMPv6
            Time Exceeded, link local address)

# TARGET

            Host/Router

# SYNOPSIS

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

# INITIALIZATION

            Before starting test, check NUT's fragment reassembly function.
            When test starts, states of Neighbor Cache Entry for TN's
            addresses are reachable.

# TEST PROCEDURE

            This test verifies that the message processing rule,

            An ICMPv6 error message MUST NOT be sent as a result of
            receiving:

            a packet destined to an IPv6 multicast address (there are
            two exceptions to this rule: (1) the Packet Too Big
            Message - Section 3.2 - to allow Path MTU discovery to
            work for IPv6 multicast, and (2) the Parameter Problem
            Message, Code 2 - Section 3.4 - reporting an unrecognized
            IPv6 option that has the Option Type highest-order two
            bits set to 10).

            TN                      NUT

            ---------------------------

            1.
             === fragmented (1st) packet  ===>
                    src address : TN link local address
                    dst address : all node multi cast address

            2.
            << JUDGMENT >>

             <=== No packet  ===
                            or
             <=== ICMPv6  Time Exceeded ===
                 Code is 1

# JUDGMENT

            << PASS >>
                    NUT do not send ICMPv6 Time Exceeded.

            << FAIL >>
                    NUT send ICMPv6 Time Exceeded.
