Re: IPv6 WG Last Call:draft-ietf-ipv6-ndproxy-02.txt

[Margaret Wasserman <margaret at thingmagic.com>]

I have a process-related concern with draft-ietf-ipv6-ndproxy-02.txt 
that I would like to discuss on this list to see what others think...

I haven't reached the point (yet) where I have a fully-formed 
objection, but I have a strong enough concern that I thought it would 
be worth some discussion before the IPv6 WG sends this document to 
the IESG.  This concern is entirely separate from any technical 
concerns that may arise when I do another full technical review of 
the document.

This document is proposed to address the following charter item:

   - Develop Proxy Neighbor Discovery solution for prefix delegation
     and publish. This enables a simple site border router to
     re-advertise downstream a prefix it hears on its upstream link.

However, it is clear that the document itself -- which proposes a 
multi-link, bridge replacement mechanism using RSTP and IPv6 
encapsulation, goes well beyond what is required to address the 
charter item.  When we agreed to include this charter item (I was an 
IPv6 WG chair at the time), I had expected a substantially 
trimmed-down version of ND Proxy that would only include the "P-bit" 
mechanism for single-step prefix delegation.

Could the current chairs perhaps comment on how they believe that the 
ND Proxy document, as it currently exists, fits within the IPv6 WG 
charter?  Is there anyone else who has an opinion on this?

This is not merely a legalistic concern.  I am concerned that the 
people who should be involved in the standardization an RSTP-based L3 
bridging technology may not be involved in the IPv6 WG.   In fact, 
they may not even be aware that this work is underway here. 
Therefore, this document may not have been developed and reviewed by 
a group that has the balance of experience needed to reach valid IETF 
consensus on this work.

Thoughts?
