=head1 SYNOPSIS
Dst_Unreach_4_Global.seq [-tooloption ...] -p
Dst_Unreach_4_Global.def
=head1 INITIALIZATION
Common Test Setup 1.1
=head1 TEST PROCEDURE
Verify that a node properly generates Destination Unreachable Messages.
This test verifies that NUT sends valid ICMPv6 Destination
Unreachable (code 4) in response to a packet which can not
be delivered to destination port.
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.
=== UDP packet ===>
src address : TN global address
dst address : NUT global address
port : not used in NUT (9000)
2.
<< JUDGEMENT >>
<=== ICMPv6 Destination Unreachable ===
Code is 4
=head1 JUDGEMENT
<< PASS >>
The NUT should send a Destination Unreachable Message to TN.
The Source Address of the Packet should be one of the NUT's unicast addresses,
while the Destination Address should be the same as the Global Source Address in TN's packet.
The Code field should be set to "4".
The invoking Echo Request packet included in the Error Message must not exceed minimum IPv6 MTU.

#
#
# =end html
#
# Unused This field is unused for all code values.
# It must be initialized to zero by the sender
# and ignored by the receiver.
#
# Description
#
# A Destination Unreachable message SHOULD be generated by a router, or
# by the IPv6 layer in the originating node, in response to a packet
# that cannot be delivered to its destination address for reasons other
# than congestion. (An ICMPv6 message MUST NOT be generated if a
# packet is dropped due to congestion.)
#
# If the reason for the failure to deliver is lack of a matching entry
# in the forwarding node's routing table, the Code field is set to 0
# (NOTE: this error can occur only in nodes that do not hold a "default
# route" in their routing tables).
#
# If the reason for the failure to deliver is administrative
# prohibition, e.g., a "firewall filter", the Code field is set to 1.
#
# If there is any other reason for the failure to deliver, e.g.,
# inability to resolve the IPv6 destination address into a
# corresponding link address, or a link-specific problem of some sort,
# then the Code field is set to 3.
#
# =begin html
#
# A destination node SHOULD send a Destination Unreachable message with
# Code 4 in response to a packet for which the transport protocol
# (e.g., UDP) has no listener, if that transport protocol has no
# alternative means to inform the sender.
