INITIALIZATION

Network Topology

          NUT(Client) 3ffe:501:ffff:100::abcd            
          |                       
          |

Verification Points

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

     RT = 2*RTprev + RAND*RTprev
     

   MRT specifies an upper bound on the value of RT (disregarding the
   randomization added by the use of RAND).  
    

     if (RT > MRT)
       RT = MRT + RAND*MRT

Configurations

TEST PROCEDURE



       NUT      TN
        |       |
        |       | NUT has been configured with IPv6 address,
        |       | and request stateless DHCPv6 service
        |       |
        | ----> |Information-request w/Option Request Option(1*)
        |       |
        | ----> |Information-request w/Option Request Option(2*)
        .       .
        .       .until RTprev = MRT + MRT*RAND 
        |       |
        | ----> |Information-request w/Option Request Option(3*)
        |       |

JUDGEMENT



  (3*)PASS: The RT must reach MRT.
