NAME

        Dst_Unreach_3_Global.seq - Address Unreachable (Routers Only)

TARGET

        Router

SYNOPSIS

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

INITIALIZATION

        Common Test Setup 1.1

TEST PROCEDURE

Verify that a node properly generates Destination Unreachable Messages

        This test verifies that RUT 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                      RUT

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

        1.
         === Echo Request packet  ===>
                src address : TN global address
                dst address : on-link address that does not exist
        2.
        << JUDGEMENT >>

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

JUDGEMENT

    << PASS >>
    The RUT should send a Destination Unreachable Message to TN.
    The Source Address of the Packet should be one of the RUT's unicast addresses,
    while the Destination Address should be the same as the Source Address in TN's Echo Request.
    The Code field should be set to "3".
    The invoking Echo Request packet included in the Error Message must not exceed minimum IPv6 MTU.
