NAME

        Time_Exc_Link-Local.seq - check Message Processing Rules (ICMPv6
         Time Exceeded , link local address)

TARGET

        Host/Router

SYNOPSIS

        Time_Exc_Link-Local.seq [-tooloption ...] -p Time_Exc_Link-Local.def

INITIALIZATION

        Before starting test, check NUT's fragment reassembly function.
        When test starts, states of Neighbor Cache Entry for TN's 
        addresses are reachable.

TEST PROCEDURE

        This test verifies that NUT sends valid ICMPv6 Time Exceeded (code 1)
        in response to a packet which can not be reassemble.
        And this test verifies that the message processing rule ,
        
    (a) If the message is a response to a message sent to one of the
        node's unicast addresses, the Source Address of the reply must
        be that same address.

                src address : TN link local address
                dst address : NUT link local address

        << JUDGMENT >>

         <=== ICMPv6  Time Exceeded ===
                src address : NUT link local address
                dst address : TN link local address
                        Code is 1

JUDGMENT

        << PASS >>
                NUT send ICMPv6 Time Exceeded.
