NAME

        To_Multi_Time_Exc.seq - Error Condition with Multicast Destination (Echo Request Reassembly Timeout)

TARGET

        Host/Router

SYNOPSIS

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

INITIALIZATION

        Common Test Setup 1.1

TEST PROCEDURE

Verify that a node properly handles the reception of an error condition caused by a packet with a Multicast Destination Address.

        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

         === fragmented (1st) packet  ===>
                src address : TN link local address
                dst address : all node link local multicast address
                     The offset of fragment is 0
                     M Flag is set

         <=== No packet  ===

JUDGEMENT

    << PASS >>
    The NUT must not send a Time Exceeded Error Message to TN1 60 seconds 
    after it receives the first fragment of an ICMPv6 Echo Request.
