TARGET

  Client

SYNOPSIS

INITIALIZATION

Network Topology

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

Verification Points

   The client transmits the message according using the following
   parameters:

      IRT   REQ_TIMEOUT 

      MRT   REQ_MAX_RT  

      MRC   REQ_MAX_RC  

      MRD   0  

   Each retransmission is based on the previous RT value 

      RT = 2*RTprev + RAND*RTprev 

   until RT > MRT. 

   After that, Each retransmission is based on MRT value 

      RT = MRT + RAND*MRT

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 
        |       |
        .       .Waiting for retransmission until RT = MRT + RAND*MRT 
        |       |
        | ----> |Request (4*)
        |       |

JUDGEMENT

  (4*)PASS: TN receives retransmitted Request.
            And RT conforms to Verification Points.

TERMINATION
