• Verification Points



   The client will receive a Reconfigure Key from the server in the
   initial Reply message from the server.  The client records the
   Reconfigure Key for use in authenticating subsequent Reconfigure
   messages.
   

   To authenticate a Reconfigure message, the client computes an
   HMAC-MD5 over the DHCP Reconfigure message, using the Reconfigure Key
   received from the server.  If this computed HMAC-MD5 matches the
   value in the Authentication option, the client accepts the
   Reconfigure message.

        |       | Initialize NUT (as a DHCPv6 client)
        |       | 
        | ----> | Information-Request w/Authentication Accept Option
        |       | and Option Request Option(Preference Option)(*1)
        | <---- | Reply with Authentication Option and Preference Option(10)
        |       | 
        |       | Preference changed from 10 to 20
        |       | Reload server configuration 
        |       | 
        | <---- | Reconfigure with comptuted Authentication(w/Authentication Option)
