INITIALIZATION

• Network Topology

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

• Verification Points



   A client sends a Release message to the server that assigned addresses
   to the client to indicate that the client will no longer use one or
   more of the assigned addresses.

   In order to test whether the client(NUT) releases address after receiving 
   Reply in response to Release, TN sends Echo Request to NUT. And NUT does
   NOT send Echo Reply to TN.
