I believe we all now agree that if the device (probably two back-to-back
routers but that’s an implementation issue) that includes the IAR function
receives an RREQ for an address inside the AODVv2 network, it should respond
normally (as you say).
There is a small but significant change here and thus in my view it is worth a
-11 posting.
Do we all agree?

Hi Stan,
I assume the IAR can still forward RREQ and RREP. I think the text means it
would not respond on behalf of the straggler, i.e. create a RREP, but it
would still forward the RREQ as any other AODVv2 router would. The straggler
would then create a RREP, and the IAR would forward the RREP as any other
AODVv2 router would...
Does "not respond" imply that it would take no action if it receives a RREQ
for an address in the AODVv2 network? If so we should say "RREQs for
addresses inside the AODVv2 network are handled using the standard AODVv2
processes described in Section ..." What do you all think?
Also, after making the change, did you want me to post to MANET as version 11?
Regards,
Vicky.

John,
I took this off-list & unicasted, because I'm not interested in stirring the
pot. But, I'm concerned about the proposed text;
The IAR MUST respond to RREQ on behalf of all Internet destinations,
i.e., destinations not on the configured 191.0.2.0/24
<http://191.0.2.0/24> subnet. The IAR
MUST be configured so that it does not respond to RREQ for addresses
within the AODVv2 manet (here, 191.0.2.0/24 <http://191.0.2.0/24>).
This means that the IAR can *never* be the neighbor that helps you discover a
route *within* the AODVv2 network - It's like an AODV instance that says "Oh,
you can get to the Internet through me, but to a node in the MANET?!? What?!?
I know NOTHING! I see NOTHING!" ;-) And, what if you get into a mobility
scenario where you have something like:
Bulk of AODVv2 net -------------- IAR ------------ One lone straggler who
turned left when he should've turned right
|
|
|
Internet
In that scenario, none of the "bulk" nodes can find the straggler, and the
straggler can't find anything other than the Internet. Or am I missing
something?
Regards,
Stan
