RADIUS Attributes for Address plus Port based Softwire Mechanisms
draft-ietf-softwire-map-radius-16
Abstract
IPv4-over-IPv6 transition mechanisms provide both IPv4 and IPv6
connectivity services simultaneously during the IPv4/IPv6 co-
existence period. DHCPv6 options have been defined for configuring
clients to use MAP-E, MAP-T, Lightweight 4over6 and Multicast Basic
Bridging BroadBand (mB4) in multicast scenarios. However, in many
networks, the configuration information may be stored in an AAA
server, while user configuration information is mainly provided by
the BNG through the DHCPv6 protocol. This document defines three new
RADIUS attributes that carry CE or mB4 configuration information from
an AAA server to BNG.
