INITIALIZATION

Network Topology

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

Verification Points

   The message exchange is terminated when the valid lifetimes of all
   the addresses assigned to the IA expire, at which time the client
   has several alternative actions to choose from; for example:

   -  The client may choose to use a Solicit message to locate a new
      DHCP server and send a Request for the expired IA to the new
      server.

   -  The client may have other addresses in other IAs, so the client
      may choose to discard the expired IA and use the addresses in the
      other IAs.

   This test check the transmission of Solicit after exchange fails.

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)
        |       |
        | ----> |Solicit
        | <---- |Advertise |Request
        | <---- |Reply w/IA_NA option(T2=80, valid-lifetime=200)
        |       |
        | <---- |Echo Request
        | ----> |Echo Reply
        |       |	
        |       |Before T2 time expires
        |       |
        | ----> |Rebind
        |       |
        |       |Before valid-lifetime time expires
        |       |
        | ----> |Solicit(8*)
        |       |

JUDGEMENT


  
  (8*)PASS: NUT transmits Solicit message.
