(Feel free to cut this introductory paragraph, however.) Please refer to https://www.ietf.org/iesg/statement/discuss-criteria.html for more information about IESG DISCUSS and COMMENT positions. The document, along with other ballot positions, can be found here: https://datatracker.ietf.org/doc/draft-ietf-v6ops-cpe-slaac-renum/ ---------------------------------------------------------------------- DISCUSS: ---------------------------------------------------------------------- Thank you for the work put into this easy-to-read document. I support Erik Kline's DISCUSS points. Please find below a couple of non-blocking COMMENT points and one nit but please also check: - Suresh Krishnan's IoT directorate review: https://datatracker.ietf.org/doc/review-ietf-v6ops-cpe-slaac-renum-05-iotdir-telechat-krishnan-2020-10-21/ - Sheng Jiang's Internet directorate review: https://datatracker.ietf.org/doc/review-ietf-v6ops-cpe-slaac-renum-05-intdir-telechat-jiang-2020-10-19/ I hope that this helps to improve the document, Regards, -éric == DISCUSS == As observed by Sheng in his review and by Rob Wilton, the use of normative-looking "MUST" is unusual in an informational document even with the section 2 about requirement languages as the use of uppercase could confuse the reader; or at least limit their use in the L-* text in section 3. Also, note that RFC 2119 has been updated by RFC 8174. The precedent set by RFC 7084 seems a bad one. I will trust the responsible AD decision on this topic. ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- The shepherd write-up includes twice "a particular corner case where DHCPv6 is being used to distribute effectively static addresses". Perhaps is it due for not being a native English speaker, but, the use of "corner case" in a shepherd write-up appears to me as weird and unexpected: is it the shepherd's opinion or the WG consensus of being a 'corner case'. I read this as 'very rare case' whereas I sincerely think, and Jordi's review indicates so, that this is not a rare case. -- Abstract -- I wonder why the word "IPv6" is never mentioned in the abstract while the whole document is about IPv6. OTOH, perhaps the default IP version in 2020 is indeed IPv6 ;-) -- Section 3 -- Should the L-13 of RFC 7084 be also updated ? Briefly discussed in section 3.3 I wonder what is the actual structure of this section? There are 4 L-XX requirements followed by 3 subsections and mapping between L-15 with section 3.1 and the same for L-16, L-17 but not for L-18 ? As noted in section 3.1, L-13 is actually Section 6.3 of [RFC8415] that is standard track -- Section 3.2 -- There is a reference to section 2.1 of this document but the authors probably meant section 3.1 of this document or Section 6.3 of [RFC8415]. Should the list of ND options include by default all options ? or at least indicate that this is not an exhaustive list to allow for future ND options ? -- Section 3.3 -- I agree with "IPv6 network renumbering is expected to take place in a planned manner," but this sentence seems to contradict the premisses of draft-ietf-v6ops-slaac-renum. Unsure how to reconciliate the two I-D (sharing some authors ;-) ). " since we acknowledge " suggest to slightly rewrite this sentence to make it less personal. Suggestion to mention whether RA are sent only on received RS, multicasted immediately (the document mention periodically), or unicasted when possible (some CPE keeps the mapping of all its unicast client notably on the Wi-Fi side).
