=head1 NAME
P_Problem_Global.seq - check Message Processing Rules (ICMPv6
Parameter Problem , global address)
=head1 TARGET
Host/Router
=head1 SYNOPSIS
P_Problem_Global.seq [-tooloption ...] -p P_Problem_Global.def
=head1 INITIALIZATION
When test starts, states of Neighbor Cache Entry for TN's
addresses are reachable.
=head1 TEST PROCEDURE
This test verifies that NUT send valid ICMPv6 Parameter Problem (code 1)
in response to a packet include unknown next header field value.
And this test verifies that the message processing rule ,
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.
TN NUT
---------------------------
1.
=== IPv6 packet ===>
src address : TN global address
dst address : NUT global address
next header is not used in NUT
2.
<< JUDGMENT >>
<=== ICMPv6 Prameter Problem ===
src address : NUT global address
dst address : TN global address
Code is 1
Pointer is 40
=head1 JUDGMENT
<< PASS >>
NUT send ICMPv6 ICMPv6 Parameter Problem.
<< FAIL >>
NUT do not send ICMPv6 Parameter Problem.
