INITIALIZATION

Network Topology

          NUT(Client)
          |           
          |                        
Link0   --+--------+------------------------ 3ffe:501:ffff:100::/64
                   |
                   |          
                   TN(Server)

Verification Points

   If addresses are declined but the Reply from a DHCP server is lost,
   the client will retransmit the Decline message, and the server may
   respond with a Reply indicating a status of NoBinding.  Therefore,
   the client does not treat a Reply message with a status of NoBinding
   in a Decline message exchange as if it indicates an error.

Configurations

`Device Name`	`Device Type`	`Interface`	`Assigned Prefix`	`Link Local Addr`	`MAC Addr`
`Client`	`NUT`	`Link0`	`3ffe:501:ffff:100::/64`	`NUT's Linklocal address`	`NUT's MAC address`
`Server`	`TN`	`Link0`	`3ffe:501:ffff:100::/64`	`fe80::200:ff:fe00:a1a1`	`00:00:00:00:a1:a1`

TEST PROCEDURE



       NUT      TN
        |       |
        |       | Initialize NUT (as a DHCPv6 Client)
        |       |

        | ----> |Decline 
        |       |
        |       | Before first RT time expires
        |       |
        | ----> |Decline 
        | <---- |Reply(W/Status code/NoBinding)
        |       |
        |       | Before RT time expires
        |       |
        | ----> |Decline (8*)
        |       |

JUDGEMENT
