IPv6 RA Options for Multiple Interface Next Hop Routes
draft-sarikaya-mif-6man-ra-route-02
Abstract
This draft defines new Router Advertisement options for configuring
next hop routes on the mobile or fixed nodes. Using these options,
an operator can easily configure nodes with multiple interfaces (or
otherwise multi-homed) to enable them to select the routes to a
destination. Each option is defined together with definitions of
host and router behaviors.

1. Introduction
IPv6 Neighbor Discovery and IPv6 Stateless Address Autoconfiguration
protocols can be used to configure fixed and mobile nodes with
various parameters related to addressing and routing [RFC4861],
[RFC4862], [RFC4191]. DNS Recursive Server Addresses and Domain Name
Search Lists are additional parameters that can be configured using
router advertisements [RFC6106].
Router Advertisements can also be used to configure fixed and mobile
nodes in multi-homed scenarios with route information and next hop
address. Different scenarios exist such as the node is
simultaneously connected to multiple access network of e.g. WiFi and
3G. The node may also be connected to more than one gateway. Such
connectivity may be realized by means of dedicated physical or
logical links that may also be shared with other users nodes such as
in residential access networks.
