# NAME

            Dst_Unreach_0_Global.seq - check ICMPv6 Destination
            Unreachable code 0

# TARGET

            Router

# SYNOPSIS

            Dst_Unreach_0_Global.seq [-tooloption ...] -p
            Dst_Unreach_0_Global.def

# INITIALIZATION

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

# TEST PROCEDURE

            This test verifies that NUT sends valid ICMPv6 Destination
            Unreachable (code 0) in response to a packet which can not
            be delivered to destination address because NUT have no route.
            And this test verifies that the message processing rule ,

            If the message is a response to a message sent to one of the
            node's unicast addresses, the Source Address of the reply must
            be that same address.

            << JUDGMENT >>

             <=== ICMPv6 Destination Unreachable ===
                    Code is 0

# JUDGMENT

            << PASS >>
                    NUT send ICMPv6 Destination Unreachable.

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