Document: draft-ietf-ipv6-ra-flags-option-01.txt Reviewer: Joel M. Halpern Review Date: 19-August-2007 IETF LC End Date: 2007-08-31 IESG Telechat date: (if known) 2007-09-06 Summary: This document is ready for publication as a proposed standard. I would change the length handling text a bit if I were writing it, so I have included that suggestion as part of my comments. There is a good chance that in this particular case all of my comments below are too picky, but they are provided for the information of the general area chair. Comments: As a general observation, it is usually a bad idea for chairs to be authors of documents in their working group. If we really don't have enough active participants in the IPv6 working group to get someone else to write this, we have a much larger problem. The document says that the length of the option is 1. This is in multiples of 8 octets, so there is lots of room. However, the text explicitly says that the length should be checked in case of future expansion. But it does not specify what to do if the length is not 1. I would recommend that the text explicitly allow for lengths greater than 1, and simply indicate that bits past those understood by the receiver are too be ignored. There could probably also be a sentence indicating that since bits are to be defined in order, this allows a receiver to properly recognize the bits it understands.
