[dhcwg] DHCPv6 client handling of NoBinding in Reply message

["Jared P. August" <jaugust at treck.com>]

Hello,

Section 18.1.8. of RFC 3315 states the following:

-----------------
When the client receives a Reply message in response to a Renew or
Rebind message, the client examines each IA independently.  For each
IA in the original Renew or Rebind message, the client:

   -  sends a Request message if the IA contained a Status Code option
      with the NoBinding status (and does not send any additional
      Renew/Rebind messages)
-----------------

I have two questions about what actions the client should take when it
receives a NoBinding as described above:
 
1. If the Reply is in response to a Renew message (meaning that the
original server has disavowed knowledge of the binding), should the
client immediately discontinue using the addresses (and maybe even send
Release messages)? Or should it continue to use the addresses, and then
send a Request for those addresses again?
 
2. If the Reply is in response to a Rebind message, and the server is
not the server that originally granted the addresses, which server
should the client send the Request to: The original server, or the new
one that just sent the NoBinding?

Thank you,
