INITIALIZATION

• Network Topology

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

• Verification Points



   The address, which have been assigned to DHCPv6 client, must has
   associated preferred and valid lifetimes specified by the server.
   To request an extension of the lifetimes assigned to an address, 
   the client sends a Renew message to the server to extend the 
   lifetimes associated with its addresses, allowing the client to
   continue to use those addresses without interruption.
   

   To test whether the client(NUT) has accepted the message from TN,
   TN sends Echo Request to NUT, and NUT sends Echo Reply to TN.
