Raj, is there a plan to deal with the interoperability issue where the 
AP tells the Station to auto-configure statelessly and the AR tells it 
statefully?

The AP may send REG-RSP telling the Station to use DHCP.

The AR may send an RA telling the Station to use SLAAC.

There may be an interoperability issue, if the two indicators are different.

This issue can of course be considered as a network management issue, 
where advice could be given to network deployers of AR and AP to 
configure their networks correctly.

And this is a time when both 802.16 is changing (Corrigendum 2 under 
discussion but still allows AP to indicate to MN what autoconf method to 
use) and the RA definition is changing (draft-2462bis indicates 'M' flag 
may not be used, but an 'autonomous' flag instead).

What do you think?  Do I get this issue correctly?  Or is the issue 
important, less important, etc.

Thanks,

Alex
