  Client

SYNOPSIS

   C_RFC3315_18_1_4_RebRetransMRT.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   REB_TIMEOUT 

      MRT   REB_MAX_RT  

      MRC   0           
 
      MRD   Remaining time until valid lifetimes of all addresses have
            expired 

   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 = RTprev + RAND*RTprev 

   if (RT > MRT)

      RT = MRT + RAND*MRT

TEST PROCEDURE

       NUT      TN
        |       | 
        |       |Initialize NUT(as a DHCPv6 client)
        |       |
        | ----> |Solicit 
        | <---- |Advertise 
        | ----> |Request 
        | <---- |Reply w/IA_NA option(T1=50, T2=80)
        |       |
        | <---- |Echo Request
        | ----> |Echo Reply
        |       |	
        |       |Wait T2 time expire
        |       |
        | ----> |Rebind
        |       |	
        .       .Repeat retransmission until RT=MRT+RAND*MRT
        |       |
        | ----> |Rebind (8*)
        |       |

JUDGEMENT

  (8*)PASS: Finally, RT for Rebind conforms to Verification Points.
