The IESG contact persons are Suresh Krishnan and Terry Manderson. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-6man-multi-homed-host/
Technical Summary This document describes expected IPv6 host behavior in a network that has more than one prefix and next-hop routers to choose from, and each prefix allocated by an upstream network/router also implements BCP 38 (RFC2827) ingress filtering. The document also applies to other deployment cases such as the usage of stateful firewalls. The solution described in the document may interact with the RFC6724 source address selection Rule 5.5. This concerns the situation where a multihomed host has multiple provider allocated addresses (formed from a Router Advertisement advertised prefixes received from multiple but not necessarily all next-hop routers) and the host should know to which router to send its traffic sourced from a given source address. Working Group Summary The document had the strong support of the 6man WG. There were no particular points of controversy. Document Quality The solution described in the document is already implemented in some form by some popular operating system IP stacks. The document does not contain MIBs, Media Types or other expert review requiring material. Personnel Jouni Korhonen is the document shepherd. Suresh Krishnan is the responsible AD.
