SYNOPSIS

   C_RFC3315_18_1_5_InfRetransMRT.seq [-tooloption...]

INITIALIZATION

Network Topology

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

Verification Points

   The client transmits the message using the following parameters:

      IRT   INF_TIMEOUT     

      MRT   INF_MAX_RT      

      MRC   0               

      MRD   0               

   RT for the first message transmission is based on IRT: 

      RT = IRT + RAND*IRT   

   RT for each subsequent message transmission is based on the previous 
   value of RT: 

      RT = 2*RTprev + RAND*RTprev 

   If (RT > MRT) 

      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)
        |       |NUT transmits Information-request  
        |       |
        | ----> |Information-request 
        |       |
        .       .Repeat retransmission until RT=MRT + RAND*MRT
        |       |
        | ----> |Information-request (2*)
        |       |
        |       |

JUDGEMENT

  (2*)PASS: NUT retransmits Information-request.
            And RT = MRT + RAND*MRT

TERMINATION

N/A
