=begin html
<PRE>
       NUT     TN
        |       | 
        |       | initialize NUT (as a Delegating router)
        |       | 
        | <---- | Solicit       (w/ IA_PD option,IA_PD Prefix option)            
        | ----> | Advertise	(w/ IA_PD option,IA_PD Prefix option)            (*1)
        | <---- | Request	(w/ IA_PD option,IA_PD Prefix option)

</PRE>

=end html

=head1 JUDGEMENT

<PRE>
(*1)(*2)PASS: The TN & NUT exchanges above messages correctly.
              And NUT will ignore the preferred lifetimes 
              That is, the values of preferred lifetimes are keep
              the original value.
