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.

This document is a product of the IPv6 Operations Working Group of the
IETF.
