Hi

We’ve just posted an update to this draft based on the comments received in WGLC. Many thanks for your reviews and suggestions.

The major changes since -01 are:

1. Rewritten abstract section
2. Provided clarification on multi-hop relays
3. Changed text related to handling of unknown messages by relays and removed req. G-2 that covered this.
4. Provided references to sections in CMTS and BNG documents
5. Added section about forwarding loops between clients and relays
6. Updated requirement R-4 to detail on avoiding the loops

I think that all of the WGLC comments are now addressed, with the exception of a question from Ole regarding implementors experience related to requirement R-4. I’ve just sent out a question on v6ops and 6man to see if we can get feedback on this.

One final question. The draft is currently called "DHCPv6 Prefix Delegating Relay” which is not particularly descriptive. We suggest changing it to ‘Requirements for DHCPv6 Prefix Delegating Relays’. Any objections to this?

Thanks,
Ian
