SYNOPSIS

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   REN_TIMEOUT    

      MRT   REN_MAX_RT     

      MRC   0              

      MRD   Remaining time until T2  

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

      RT = 2*RTprev + RAND*RTprev 

   If (RT > MRT)  

      RT = MRT + RAND*MRT

TEST PROCEDURE

       NUT      TN
        |       | 
        |       |Initialize NUT(as a DHCPv6 client)
        | ----> |Solicit

        | ----> |Request 
        | <---- |Reply w/IA_NA option (T1=40, T2=2000)
        |       |

        | ----> |Echo Reply
        |       |	
        |       |Before T1 time expires
        |       |	 
        | ----> |Renew 
        |       |
        |       |Waiting for DHCPv6 message until RT=MRT+RAND*MRT
        |       |
        | ----> |Renew (8*)
        |       |
