TEST PROCEDURE

       NUT     TN
        |       | 
        |       | initialize NUT (as a DHCPv6 Server)
        |       | 
        | <---- | Information-request(w/ Option Request option)
        | ----> | Reply (w/ Server ID option) (*1)
        |       | 
         reboot 
        |       | 
        | <---- | Information-request(w/ Option Request option)
        | ----> | Reply (w/ Server ID option) (*2)

JUDGEMENT

(*1)PASS: The DUID's  format in the Server's Identifier option of Reply 
    message must be base on description of RFC(see above Verification Points).
(*2)PASS: After restarting, the DUID must be keeped.
