NAME

        MPR_e2_dst_unr.seq - check Message Processing Rules (ICMPv6
         Destination Unreachable )


TARGET

        Host and Router


SYNOPSIS

        MPR_e2_dst_unr.seq [-tooloption ...] -p MPR_e2_dst_unr.def


INITIALIZATION

        When test stars, states of Neighbor Cache Entry for TN's 
        addresses are reachable.


TEST PROCEDURE

        This test verifies that the message processing rule ,
        
    (e) An ICMPv6 error message MUST NOT be sent as a result of
        receiving:

         (e.2) 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), or

        TN                      NUT

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

        1.
         === UDP packet  ===>
                src address : TN link local address
                dst address : all node multicast address
             port number is not used in NUT
        2.
        << JUDGMENT >>

         <=== No pakcet ===
                        or
         <=== ICMPv6 Destination Unreachable ===
             Code is 4


JUDGMENT

        << PASS >>
                NUT do not send ICMPv6 Destination Unreachable.
                
        << FAIL >>      
                NUT send ICMPv6 Destination Unreachable.
