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.1) an ICMPv6 error message, or

        TN                      NUT

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

        1.
         === ICMPv6 Destination Unreachable  ===>
                src address : TN global address
                dst address : OFFLINK address
                code        : port unreachable
        2.
                NUT can't deliver to destination address.
                (NUT have not route for the dst address.)
        3.
        << JUDGMENT >>
        
         <=== No packets ===
                        or      
         <=== ICMPv6 Destination Unreachable ===
             Code is 4

JUDGMENT

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

        << FAIL >>      
                NUT send ICMPv6 Destination Unreachable.
