We have posted a revision of draft-gont-6man-slaac-renum. It is
This document proposes IPv6 SLAAC protocol updates to improve the
robustness of SLAAC in the presence of renumbering events.
The main changes incorporated in this version are:
* We have eliminated the counter-based algorithm from Section 4.5
Previous revisions of the draft contained two alternative algorithms in
Section 4.5: a counter-based algorithm, and a timer-based algorithm. The
timer-based algorithm is more robust and simple, so it didn't make sense
to keep the counter-based algorithm. (Kudos to Philip Homburg for
"pushing" us to improve the algorithm).
* Clarified the terminology used in the document
This is a rather minor detail. We simply have spelled out that
throughout the document, "GUAs" refer to "globally reachable" addresses
(as opposed to ULAs).

As always, your feedback will be appreciated.

Title: Improving the Robustness of Stateless Address Autoconfiguration
(SLAAC) to Flash Renumbering Events
Document date: 2020-05-18
Group: Individual Submission
In renumbering scenarios where an IPv6 prefix suddenly becomes
invalid, hosts on the local network will continue using stale
prefixes for an unacceptably long period of time, thus resulting in
connectivity problems. This document improves the reaction of IPv6
Stateless Address Autoconfiguration to such renumbering scenarios.
