INITIALIZATION

• Network Topology

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

• Verification Points



   An "identity-association" (IA) is a construct through which a server
   and a client can identify, group, and manage a set of related IPv6
   addresses.  Each IA consists of an IAID and associated configuration
   information.The IAID uniquely identifies the IA and must be chosen to
   be unique among the IAIDs on the client.  The IAID is chosen by the
   client. For any given use of an IA by the client, the IAID for that IA
   MUST be consistent across restarts of the DHCP client.

   IA_NA option includes IAID. So check the consistence of IAID field of
   IA_NA option after client reboots.
   

    
option-code is OPTION_IA_NA(3)
 
    
IAID is ANY Non-zero number
   
   

• Configurations




Device Name	Device Type	Interface	Assigned Prefix	Link Local Addr	MAC Addr
Client	NUT	Link0	3ffe:501:ffff:100::/64	NUT's Linklocal address	NUT's MAC address
Server	TN	Link0	3ffe:501:ffff:100::/64	fe80::200:ff:fe00:a1a1	00:00:00:00:a1:a1

TEST PROCEDURE

       NUT      TN
        |       | 
        |       |Initialize NUT (as a DHCPv6 Client)
        |       | 
        | ----> |Solicit (1*)
        |       | 
        |       |Reboot  NUT
        |       |
        | ----> |Solicit (2*)
        |       |

JUDGEMENT

  (2*)PASS: the value of IAID should be same with that of (1*).
