=head1 NAME
To_Multi_Time_Exc.seq - check Message Processing Rules (ICMPv6
Time Exceeded, link local address)
=head1 TARGET
Host/Router
=head1 SYNOPSIS
To_Multi_Time_Exc.seq [-tooloption ...] -p To_Multi_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,
An ICMPv6 error message MUST NOT be sent as a result of
receiving:
a packet destined to an IPv6 multicast address (there are
two exceptions to this rule: (1) the Packet Too Big
Message - Section 3.2 - to allow Path MTU discovery to
work for IPv6 multicast, and (2) the Parameter Problem
Message, Code 2 - Section 3.4 - reporting an unrecognized
IPv6 option that has the Option Type highest-order two
bits set to 10).
TN NUT
---------------------------
1.
=== fragmented (1st) packet ===>
src address : TN link local address
dst address : all node multi cast address
2.
<< JUDGMENT >>
<=== No packet ===
or
<=== ICMPv6 Time Exceeded ===
Code is 1
=head1 JUDGMENT
<< PASS >>
NUT do not send ICMPv6 Time Exceeded.
<< FAIL >>
NUT send ICMPv6 Time Exceeded.
