NAME

        To_Multi_Dst_Unreach_4.seq - Error Condition with Multicast Destination (UDP Port Unreachable)

TARGET

        Host/Router

SYNOPSIS

        To_Multi_Dst_Unreach_4.seq [-tooloption ...] -p To_Multi_Dst_Unreach_4.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).

JUDGEMENT

    << PASS >>
    The NUT must not send a Destination Unreachable Error Message to TN1 
    when it receives a UDP packet for an unreachable port.
