Dst_Unreach_3_Global.seq - check ICMPv6 Destination
Unreachable code 3
=head1 TARGET
Router
=head1 SYNOPSIS
Dst_Unreach_3_Global.seq [-tooloption ...] -p
Dst_Unreach_3_Global.def
=head1 NETWORK CONFIGURATION
This test is OFF-LINK Network Configuration test.
Physical Network configuration
---------------------------------------

NUT TN
Logical Network Configuration
TN

----------------------------------

NUT

----------------------------------

OFFLINKA Host
=head1 INITIALIZATION
When test stars, configure a default route with TN as the next hop.
And states of Neighbor Cache Entry for TN's addresses are reachable.
=head1 TEST PROCEDURE
This test verifies that NUT sends valid ICMPv6 Destination
Unreachable (code 3) in response to a packet which can not
be delivered to destination address (e.g. Address Resolution
in ND).
TN NUT
---------------------------
1.
=== Echo Request packet ===>
src address : TN global address
dst address : on-link unreachable address
2.
<< JUDGEMENT >>
<=== ICMPv6 Destination Unreachable ===
Code is 3
=head1 JUDGEMENT
<< PASS >>
NUT send ICMPv6 Destination Unreachable.
<< FAIL >>
NUT do not send ICMPv6 Destination Unreachable.

# =begin html
#
# Code 0 - no route to destination
# 1 - communication with destination
# administratively prohibited
# 2 - (not assigned)
# 3 - address unreachable
# 4 - port unreachable
#
#
# =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.)
#
# 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.
#
# =begin html
#
# If the reason for the failure to deliver is lack of a matching entry
# 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.
#
#
# =end 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.
