Hi,

I believe that this is an important topic that 6MAN should take up. The draft is a good basis.

At the moment I find the draft a bit confusing in one way. It's aimed at standards track, but it mainly doesn't read like a standard. There's a lot of discussion but not much specification. If I was a coder, I wouldn't really know where to start. For example, the end of the Introduction says:

"This document discusses the applicability of IPv6 ND
 over wireless links, as compared with routing-based alternatives such
 as prefix-per node and multi-link subnets (MLSN), and with Wireless
 ND (WiND), that is similar to the Wi-Fi association and reduces the
 need for Network-Layer multicast."

If it's a standard, IMHO it shouldn't do that. It should specify what WiND is, with normative references as needed. Section 5 is the important part. It's fine to have a descriptive section about why WiND is needed, but that is almost better as an appendix. The main text should be essentially the instructions for a kernel programmer.

Regards
   Brian Carpenter
