Folks, We have posted a new I-D discussing a problem that can arise in typical deployment scenarios where the CPE obtains a prefix via DHCPv6-PD and advertises a prefix on the LAN side. We also propose a solution to the aforementioned problem. Our draft is available at: https://tools.ietf.org/html/draft-gont-6man-slaac-renum The Abstract is: A very common IPv6 deployment scenario is that in which a CPE employs DHCPv6 Prefix Delegation to obtain an IPv6 prefix, and at least one prefix from within the leased prefix is advertised on a local network via SLAAC. In scenarios where e.g. the CPE crashes and reboots, nodes on the local network continue using outdated prefixes which result in connectivity problems. This document analyzes this problem scenario, and proposes workarounds. Any comments will be welcome. Thanks!
