The IESG has received a request from the IPv6 Operations WG (v6ops) to consider the following document: - 'Close encounters of the ICMP type 2 kind (near misses with ICMPv6 PTB)' <draft-ietf-v6ops-pmtud-ecmp-problem-04.txt> as Informational RFC The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2015-09-30. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract This document calls attention to the problem of delivering ICMPv6 type 2 "Packet Too Big" (PTB) messages to the intended destination (typically the server) in ECMP load balanced or anycast network architectures. It discusses operational mitigations that can be employed to address this class of failures. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-v6ops-pmtud-ecmp-problem/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-v6ops-pmtud-ecmp-problem/ballot/ No IPR declarations have been submitted directly on this I-D.
