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.

#    Pointer        Identifies the octet offset within the
#                   invoking packet where the error was detected.
# 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.
#
# # =end html # # 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.
