NAME

        Dst_Unreach_2.seq - Beyond Scope of Source Address (Routers Only)

TARGET

        Router

SYNOPSIS

        Dst_Unreach_2.seq [-tooloption ...] -p 
        Dst_Unreach_2.def

INITIALIZATION

        Common Test Setup 1.1

TEST PROCEDURE

Verify that a node properly generates Destination Unreachable Messages

        This test verifies that NUT sends valid ICMPv6 Destination 
        Unreachable (code 2) in response to a packet when the scope of
        the source address is smaller than the scope of the destination
        address and the packet cannot be delivered to the destination
        without leaving the scope of the source address.

        TN                      RUT

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

        1.
         === Echo Request  ===>
                src address : TN link-local address
                dst address : offlink address
        2.
        << JUDGEMENT >>

         <=== ICMPv6 Destination Unreachable ===
                Code is 2

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 "2".
    The invoking Echo Request packet included in the Error Message must not exceed minimum IPv6 MTU.
