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.
