=head1 NAME
P_Problem_Global.seq - check Parameter Problem (global address)
=head1 TARGET
Host/Router
=head1 SYNOPSIS
P_Problem_Global.seq [-tooloption ...] -p P_Problem_Global.def
=head1 INITIALIZATION
If the NUT is a host, send a Router Advertisment.
If the NUT is a router, configure a default route with TN as the next hop.
And make state of Neighbor Cashe Entry for TN's addresses 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.
<< JUDGEMENT >>
<=== ICMPv6 Prameter Problem ===
src address : NUT global address
dst address : TN global address
Code is 1
Pointer is 40
=head1 JUDGEMENT
<< PASS >>
NUT send ICMPv6 Parameter Problem.
<< FAIL >>
NUT do not send ICMPv6 Parameter Problem.

# The pointer will point beyond the end of the ICMPv6 # packet if the field in error is beyond what can fit # in the maximum size of an ICMPv6 error message. #
# 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. ## # =end html # =pod =head1 REFERENCE =begin html
