Please send substantive comments to the ietf@ietf.org mailing lists by 2017-03-01. 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 describes Path MTU Discovery for IP version 6. It is largely derived from RFC 1191, which describes Path MTU Discovery for IP version 4. It obsoletes RFC1981. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-6man-rfc1981bis/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-6man-rfc1981bis/ballot/ No IPR declarations have been submitted directly on this I-D. The document contains these normative downward references. See RFC 3967 for additional information: rfc4443: Internet Control Message Protocol (ICMPv6) for the Internet Protocol Version 6 (IPv6) Specification (Draft Standard - IETF stream) Note that some of these references may already be listed in the acceptable Downref Registry.
