   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:<BR>

=head1 TEST PROCEDURE

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

=end html

=head1 JUDGEMENT

<PRE>
(*1) PASS: The Advertise message must include Server ID option.
           And the format of options must be based on the RFC's description.
           (see the above Verification Points )
