Los comentarios son bienvenidos. Y quienes quieran/puedan participar del llamado a adopción, mas aun. Saludos, y gracias! Fernando -------- Forwarded Message -------- Subject: (fwd) Adoption Call for "Improving the Robustness of Stateless Address Autoconfiguration (SLAAC) to Flash Renumbering Events" Date: Sun, 28 Jun 2020 22:58:02 -0300 From: Fernando Gont To: IPv6 Hackers Mailing List Folks, The 6man chairs have started a WG call for adoption of our document "Improving the Robustness of Stateless Address Autoconfiguration (SLAAC) to Flash Renumbering Events" (https://www.ietf.org/id/draft-gont-6man-slaac-renum-08.txt) Our document proposes protocol improvements such that SLAAC can gracefully deal with renumbering events. The associated problem statement can be found here: https://tools.ietf.org/html/draft-ietf-v6ops-slaac-renum If you have comments/feedback/opinions on the topic and/or about the adoption of our document as a 6man wg item, please consider participating in the ongoing consensus call: https://mailarchive.ietf.org/arch/msg/ipv6/YBnHoe9yqw0Five6ckAjDWgMpyE/ Please also check the clarifications I've made regarding the adoption call: https://mailarchive.ietf.org/arch/msg/ipv6/XfUtieXhAACPj92noFPD8XjuF-Q/ Thanks!

Gont, J. Zorz, R. Patterson File Name: draft-gont-6man-slaac-renum-08 Document date: 2020-05-18 https://tools.ietf.org/html/draft-gont-6man-slaac-renum as a working group item. Substantive comments and statements of support for adopting this document should be directed to the mailing list. Editorial suggestions can be sent to the authors. This adoption call will end on 10 July 2020. There has been a lot of discussion on this draft, the chairs have some concerns with this document being adopted, but wanted the w.g. to express its opinion. Our concerns include: This document proposes significant changes to SLAAC to fix what could be seen as an implementation problem in some edge routers. This will affect all IPv6 nodes, not only the ones communicating with these edge routers. This part of IPv6 is a mature standard. It is not clear we should modify all IPv6 hosts to deal with one corner case that may break other things allowed by the standard. The changes proposed will make SLAAC more active, the changes include: o Reducing the default Valid Lifetime and Preferred Lifetime of PIOs o Caps the received Valid Lifetime and Preferred Lifetime of PIOs. o Frequent retransmission of configuration information o Routers send all options in RA messages Some additional questions for the w.g. to consider: o Are there better approaches to address the underlying issue? o Do the proposed changes work in all deployments? o Are some proposed changes worth advancing even if the entirety may not be? If so, which ones? We would like the w.g. to consider and comment on these issues when responding to this adoption call. Bob & Ole 6man co-chairs
