Re: [ipwave] I-D Action: draft-ietf-ipwave-vehicular-networking-26.txt

Hi, I started reviewing this and found that it has been completely overhauled since I put my
comments in many months ago. It has in fact been completely rewritten to favor the shared
IPv6 multilink subnet model over multihop networks, to favor RPL/6LowPan over standard
MANET routing protocols, to favor IPv6 ND changes over standard IPv6 ND, and to favor
multilink DAD. None of that is necessary with AERO/OMNI and the NBMA-based virtual link
created by the OMNI Adaptation. So, I stopped midway through marking up the document
with my comments because it has taken a complete left turn and started down a wrong path.

What is mainly at the heart of the divergence is that the document now embraces the
multilink IPv6 subnet model vs the AERO/OMNI NBMA link model that was there the last
time I looked. But, there is no need for such complication when there is a much simpler
alternative at hand. I notice also that in the appendices the AERO/OMNI "6M's of Mobile
Internetworking" was removed - at the very least that needs to be restored.

In its current form, this document has been diverted to go down the wrong path. It
needs to be either re-balanced or re-written.

Thanks - Fred
