INITIALIZATION

• Network Topology

          TN(Client1)  
             |
Link0 -------+-----------+--------------- 3ffe:501:ffff:100::/64

• Verification Points

   The Server Identifier option is used to carry a DUID (see section 9)
   identifying a server between a client and a server.  The format of
   the Server Identifier option is:

       0                   1                   2                   3
       0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1

      option-code   OPTION_SERVERID (2). 

      option-len    Length of DUID in octets. 

      DUID          The DUID for the server. 

• Configuration

Device Name	Device Type	I/F	Assigned Prefix	Link Local Addr	MAC Addr
Server1	NUT	Link0	3ffe:501:ffff:100::/64	NUT's Linklocal address	NUT's MAC address
Client1	TN	Link0	3ffe:501:ffff:100::/64	fe80::200:ff:fe00:a2a2	00:00:00:00:a2:a2

TEST PROCEDURE

       NUT      TN
        |       | 
        |       | initialize NUT (as a DHCPv6 Server)
        |       | 
        | <---- | Solicit
        | ----> | Advertise   (w/ Server ID) (*1)
        |       |
