INITIALIZATION

Network Topology

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

Verification Points

   The client sets the "msg-type" field to DECLINE.

   The client generates a transaction ID and places this value in the
   "transaction-id" field.

   The client places the identifier of the server that allocated the
   address(es) in a Server Identifier option. 

   The client MUST include a Client Identifier option to identify itself
   to the server.  

   The client includes options containing the IAs for the addresses it
   is declining in the "options" field.  The addresses to be declined
   MUST be included in the IAs.
