=head1 INITIALIZATION

	Perform Common Test Setup 1.1.

=head1 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  Parameter Problem  ===>
                src address : TN global address
                dst address : Off-link address
                code : 0

	2.
	<< JUDGEMENT >>

	 <=== No packets ===
                   or      
	 <=== ICMPv6 Time Exceeded ===
                code : 0


=head1 JUDGEMENT

	<< PASS >>
		NUT do not send ICMPv6 Time Exceeded.

	<< FAIL >>	
		NUT send ICMPv6 Time Exceeded.
