INITIALIZATION

        Common Test Setup 1.1

TEST PROCEDURE

        Verify that a node properly replies to ICMPv6 Echo Requests.

        This test verifies that NUT receives valid ICMPv6 Echo Request 
        and sent ICMPv6 Echo Reply.

        TN                      NUT

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

        1.
         === ICMPv6 Echo Request ===>
                        src address : TN link local address
                        dst address : all routers link local multicast address        
        2.
        << JUDGEMENT >>

         <=== ICMPv6 Echo Reply ===
                        src address : NUT global or link local address
                        dst address : TN link local address

JUDGEMENT

    << PASS >>
    The NUT should send an Echo Reply to TN. 
    The Source Address of the Packet must be one of the NUT's unicast addresses 
    belonging to the interface on which the Echo Request was received.
    This could be either a Link-Local or Global address.
    The  Destination Address must be TN's local address Echo Request packet.
    The NUT must send an Echo Reply to TN with a valid checksum.
