INITIALIZATION

• Network Topology

          TN(Requesting router1)  
             |
Link0 -------+-----------+--------------- 3ffe:501:ffff:100::/64
                         |
                       NUT(Delegating router1)
  

      
Verification Points
If a delegating router receives an IA_PD with T1 greater than T2, and
both T1 and T2 are greater than 0, the delegating router ignores the
invalid values of T1 and T2 and processes the IA_PD as though the
delegating router had set T1 and T2 to 0.
The Delegating router runs like the case "T1=0 & T2=0",
That is, the parameters is determined by the client.
Format of IA_PD option in the Reply

OPTION_IA_PD (25)
option-length
12 + length of IA_PD-options field.
IAID
Same as the Request.
T1
Same as the Request.
T2
Same as the Request.

Device Name	Device Type	I/F	Assigned Prefix	Link Local Addr	MAC Addr
Delegating router1	NUT	Link0	3ffe:501:ffff:100::/64	NUT's Linklocal address	NUT's MAC address

TEST PROCEDURE

       NUT     TN
        |       | 
        |       | initialize NUT (as a Delegating router)
        |       | 
        | <---- | Solicit       (w/ IA_PD option) T1>T2>0          
        | ----> | Advertise	(w/ IA_PD option)           
        | <---- | Request       (w/ IA_PD option)             
        | ----> | Reply	(w/ IA_PD option)             (*1)
        |       | 

JUDGEMENT

(*1)PASS: The TN & NUT exchanges above messages correctly.
           And NUT will ignore the T1, T2.
           That is, the value of fileds of IA_PD option is same as the Request message.
           or
           Return Reply message without IA_Prefix option.
