=head1 SYNOPSIS
P_Problem_Global.seq [-tooloption ...] -p P_Problem_Global.def
=head1 INITIALIZATION
Common Test Setup 1.1
=head1 TEST PROCEDURE
Verify that a node properly generates Parameter Problem Message when an Unrecognized Next Header type is encountered.
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
Destination Option Header : next header(128) is not used in NUT
2.
<< JUDGEMENT >>
<=== ICMPv6 Prameter Problem ===
src address : NUT global address
dst address : TN global address
Code is 1
Pointer is 40
=head1 JUDGEMENT
<< PASS >>
The NUT must discard the ICMPv6 Echo Request from TN.
Therefore, it must not send an Echo Reply.
The NUT should send a Parameter Problem Meesage to TN
with a code field valude of 1 (Unrecognized Next Header type encountered)
The Pointer Field should be 0x28 (offset of the Next Header field).
The Source Address of the Packet must be the same as
the Global Destination Address of TN's Echo Request packet.

#
# Description
#
# =begin html
#
# If an IPv6 node processing a packet finds a problem with a field in
# the IPv6 header or extension headers such that it cannot complete
# processing the packet, it MUST discard the packet and SHOULD send an
# ICMPv6 Parameter Problem message to the packet's source, indicating
# the type and location of the problem.
#
#
# =end html
#
# =begin html
#
# The pointer identifies the octet of the original packet's header
# where the error was detected. For example, an ICMPv6 message with
# Type field = 4, Code field = 1, and Pointer field = 40 would indicate
# that the IPv6 extension header following the IPv6 header of the
# original packet holds an unrecognized Next Header field value.
