NAME

        Err_Msg_Size_Dst_Unreach_4.seq - check Message Processing Rules (ICMPv6
        Destination Unreachable , link local address)


TARGET

        Host/Router


SYNOPSIS

        Err_Msg_Size_Dst_Unreach_4.seq [-tooloption ...] -p Err_Msg_Size_Dst_Unreach_4.def


INITIALIZATION

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


TEST PROCEDURE

        This test verifies that the message processing rule ,
        
        Every ICMPv6 error message (type < 128) includes as much of the
        IPv6 offending (invoking) packet (the packet that caused the
        error) as will fit without making the error message packet
        exceed the minimum IPv6 MTU [IPv6].

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

        1.
         === UDP packet  ===>
             port number is not used in NUT
                packet size is 1280 octets
        2.
        << JUDGMENT >>

         <=== ICMPv6 Destination Unreachable ===
                Code is 4
                        packet size is 1280 octets


JUDGMENT

        << PASS >>
                NUT send ICMPv6 Destination Unreachable.
                

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