The IESG has approved the following document: - 'SNAC Router Flag in ICMPv6 Router Advertisement Messages' (draft-ietf-6man-snac-router-ra-flag-07.txt) as Proposed Standard
This document is the product of the IPv6 Maintenance Working Group. The IESG contact persons are Éric Vyncke and Tommy Jensen. A URL of this Internet-Draft is: https://datatracker.ietf.org/doc/draft-ietf-6man-snac-router-ra-flag/ Technical Summary This document defines a new flag, the SNAC Router flag, in the Router Advertisement message that can be used to distinguish configuration information sent by SNAC routers from information sent by infrastructure routers. This flag is used only by SNAC routers and is ignored by all other devices. Working Group Summary The document has been extensively discussed on the list and during 6MAN sessions for the last few IETFs. It should be noted that the document just defines a single bit, while all details about sematnics of that bit are in scope for the SNAC WG. So the support was expressed mostly by participants who are active in both areas (6man and snac), but it was a broad agreement between them that the document is useful (even crucial for SNAC) and shall be moved forward. The document was retuned to the 6MAN working to resolve an issue with a normative reference to <draft-ietf-snac-simple>. After discussion at the last IETF meeting and on the list, a way to make that reference Informative was developed, the current version does that. The changes can be seen in this diff: https://author-tools.ietf.org/iddiff?url1=draft-ietf-6man-snac-router-ra-flag-03&url2=draft-ietf-6man-snac-router-ra-flag-04&difftype=--html A new working group last call was completed on 2026-04-23. This resulted in a few other changes to clarify the document. The chairs believe there is a consensus to advance again the document to the IESG. Document Quality The OpenThread project already implements this: https://github.com/openthread/openthread The author believes that practically all Thread-based products (including Thread Border Routers in-market and in-development) incorporate the OpenThread implementation. Personnel The Document Shepherd for this document is Jen Linkova. The Responsible Area Director is Éric Vyncke. IANA Note IANA is requested to allocate an RA flag (see section 4). _______________________________________________ IETF-Announce mailing list -- [email protected] To unsubscribe send an email to [email protected]
