            Unreachable code 3

# TARGET

            Host and Router

# SYNOPSIS

            Dst_Unreach_3_Global.seq [-tooloption ...] -p

# NETWORK CONFIGURATION

            This test is OFF-LINK Network Configuration test.

# INITIALIZATION

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

# TEST PROCEDURE

            This test verifies that NUT sends valid ICMPv6 Destination
            Unreachable (code 3) in response to a packet which can not
            be delivered to destination address (e.g. Address Resolution
            in ND).

            TN                      NUT

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

            1.
             === Echo Request packet  ===>
                    src address : TN link local address
                    dst address : NUT Link1 unreachable address
            2.
            << JUDGMENT >>

             <=== ICMPv6 Destination Unreachable ===
                    Code is 3

# JUDGMENT

            << PASS >>
                    NUT send ICMPv6 Destination Unreachable.

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