   option-code:      OPTION_IA_PD (25)  

   option-length:    12 + length of IA_PD-options field. 

   IAID:             The unique identifier for this IA_PD; the IAID must
                     be unique among the identifiers for all of this
                     requesting router's IA_PDs.

   T1:               The time at which the requesting router should
                     contact the delegating router from which the
                     prefixes in the IA_PD were obtained to extend the
                     lifetimes of the prefixes delegated to the IA_PD;
                     T1 is a time duration relative to the current time
                     expressed in units of seconds.

   T2:               The time at which the requesting router should
                     contact any available delegating router to extend
                     the lifetimes of the prefixes assigned to the
                     IA_PD; T2 is a time duration relative to the
                     current time expressed in units of seconds.

   IA_PD-options:    Options associated with this IA_PD.
