                NUT             TN

INITIALIZATION

        Perform Common Test Setup 1.1.
        Make a Neighbor Cache Entry for TN's in NUT.

TEST PROCEDURE

        This test verifies that the message processing rule,

        An ICMPv6 error message MUST NOT be sent as a result of
        receiving an ICMPv6 error message.

                src address:    TN link-local address
                dst address:    On-link unreachable address
                code:           0 (no route to destination)

JUDGEMENT

        << PASS >>
                NUT don't send ICMPv6 Destination Unreachable.

        << FAIL >>
                NUT send ICMPv6 Destination Unreachable.
