Reaction of IPv6 Stateless Address Autoconfiguration to Flash-Renumbering Events
RFC 8978, “Reaction of IPv6 Stateless Address Autoconfiguration to Flash-Renumbering Events”, is an Informational document published in March 2021 by F. Gont, J. Žorž, R. Patterson. The canonical text is published by the RFC Editor.
Abstract
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.
What “Informational” means
Published for the general information of the community. It does not define an IETF standard and carries no standards-track status.
