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 sents valid ICMPv6 Echo Request .

If the node has more than one unicast address, it must # choose the Source Address of the message as follows: # # (a) 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. # # (b) If the message is a response to a message sent to a multicast or # anycast group in which the node is a member, the Source Address # of the reply must be a unicast address belonging to the # interface on which the multicast or anycast packet was received. # # (c) If the message is a response to a message sent to an address # that does not belong to the node, the Source Address should be # that unicast address belonging to the node that will be most # helpful in diagnosing the error. For example, if the message is # a response to a packet forwarding action that cannot complete # successfully, the Source Address should be a unicast address # belonging to the interface on which the packet forwarding # failed. # # (d) Otherwise, the node's routing table must be examined to # determine which interface will be used to transmit the message # to its destination, and a unicast address belonging to that # interface must be used as the Source Address of the message. # # # 4.1 Echo Request Message # # 0 1 2 3 # 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 # +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ # | Type | Code | Checksum | # +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ # | Identifier | Sequence Number | # +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ # | Data ... # +-+-+-+-+- # # IPv6 Fields: # # =begin html #
