=head1 NAME
Err_Msg_Size_Time_Exc.seq - check Message Processing Rules (ICMPv6
Time Exceeded , link local address)
=head1 TARGET
Host/Router
=head1 SYNOPSIS
Err_Msg_Size_Time_Exc.seq [-tooloption ...] -p Err_Msg_Size_Time_Exc.def
=head1 INITIALIZATION
Before starting test, check NUT's fragment reassembly function.
When test starts, states of Neighbor Cache Entry for TN's
addresses are reachable.
=head1 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].
TN NUT
---------------------------
1.
=== fragmented (1st) packet ===>
packet size is 1280 octets
2.
<< JUDGMENT >>
<=== ICMPv6 Time Exceeded ===
Code is 1
packet size is 1280 octets
=head1 JUDGMENT
<< PASS >>
NUT send ICMPv6 Time Exceeded.
<< FAIL >>
NUT do not send ICMPv6 Time Exceeded.
