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  Time Exceeded  ===>
         src address : TN global address
         dst address : Off-link unreachable address

        2.
        << JUDGEMENT >>

         <=== No packets ===
                   or      
         <=== ICMPv6 Destination Unreachable ===
             Code is 0

JUDGEMENT

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

        << FAIL >>      
                NUT send ICMPv6 Destination Unreachable.
