(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: ---------------------------------------------------------------------- [ section 3.2 ] * I absolutely agree in principle at these other lifetimes should be updated to the shorter of the two applicable lifetimes, but I'm worried that this text is not sufficiently precise. Specifically, this recommendation only applies to options that depend in any way on the change in the delegated prefix, yes? Perhaps just this qualifier is sufficient? For example, none of these comparative lifetime recommendations apply to a stable ULA for a router that meets requirements ULA-[1..5] and chooses to advertise a ULA /48 RIO and maybe even a ULA DNS server, I think. That being said, should this document also be saying that the ULA-derived options SHOULD prefer the ND_{P,V}_LIMIT lifetime values, in case a reboot causes a new ULA to be generated (i.e. the one supposedly in stable storage is lost or otherwise unrecoverable)? ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- [[ comments ]] [ section 3.1 ] * With respect to the second bullet: the lifetimes need to be dynamically *updateable*, not necessarily updated if, for example, the ND_{P,V}_LIMIT values are always lower than the remaining PD lifetimes. In this situation, the requirement is still that the lifetimes can be updated, but to the casual observer of the steady state the RA contents might appear static (e.g., while the PD'd prefix is continuously renewed). Maybe there's no text required here, but I didn't want a reader to be left with the impression that no two RAs could be identical [[ nits ]] [ section 3.3 ] * In the 2nd bullet's 2nd bullet (this might be easier if these lists were numbered), it might be good to clarify that "the *deprecated* prefix can simply be advertised..."
