[dhcwg] About draft No. 22

["Dany JUNG" <[e-mail]>]

Hi all~
 
While I was reading draft-22.txt, I got to have several questions. 
I would like to ask you all and share information as a fellow from now
on.
I have been an observer, although this is a great community.
I would love to work more actively.
 
1. Why does Reply message have DUID option in this chart?
 
 B. Appearance of Options in Message Types
 
   The following table indicates with a "*" the options are allowed in
   each DHCP message type:
 
 
        DUID   IA    RTA   ORO  Pref  Time Client Server DSTM  DSTM
                                             Forw.  Forw. Addr  Tunn
Solicit    *     *     *     *

R-forw.                                        *     *
R-repl.                                        *     *
 
 
2. What do you configure for reply message's options if you are
questioned to assign IPv6 address and 
IPv4 address for DSTM in request message simultaneously ?
 
 
Options of Reply message are as follow
-IA option
-IA Address option
-DSTM Global IPv4 address option
-IA option (for IPv4-mapped IPv6 address)
-IA Address option  (for IPv4-mapped IPv6 address)
 
Is this possible?? 
 
 
To work more actively, I am going to ask you more questions, and look
forward to hearing from you.
I will try to reply your questions as many as I can.
 
 
Have a nice day !!
