Reaction of IPv6 Stateless Address Autoconfiguration (SLAAC) to Flash-Renumbering Events
RFC 8978

Received changes through RFC Editor sync (created alias RFC 8978, changed title to 'Reaction of IPv6 Stateless Address Autoconfiguration (SLAAC) to Flash-Renumbering Events', changed abstract to 'In scenarios where network configuration information related to IPv6 prefixes becomes invalid without any explicit and reliable signaling of that condition (such as when a Customer Edge router crashes and reboots without knowledge of the previously employed prefixes), hosts on the local network may continue using stale prefixes for an unacceptably long time (on the order of several days), thus resulting in connectivity problems.  This document describes this issue and discusses operational workarounds that may help to improve network robustness.  Additionally, it highlights areas where further work may be needed.', changed pages to 11, changed standardization level to Informational, changed state to RFC, added RFC published event at 2021-03-10, changed IESG state to RFC Published)
