    RADIUS Attribute for Softwire Address plus Port based Mechanisms
                   draft-ietf-softwire-map-radius-10

Abstract

   IPv4-over-IPv6 transition mechanisms provide both IPv4 and IPv6
   connectivity services simultaneously during the IPv4/IPv6 co-existing
   period.  The Dynamic Host Configuration Protocol for IPv6 (DHCPv6)
   options have been defined to configure Customer Edge (CE) in MAP-E,
   MAP-T, and Lightweight 4over6.  However, in many networks, the
   configuration information may be stored in the Authentication
   Authorization and Accounting (AAA) servers, while user configuration
   is mainly provided by the Broadband Network Gateway (BNG) through the
   DHCPv6 protocol.  This document defines a Remote Authentication Dial
   In User Service (RADIUS) attribute that carries CE configuration
   information from the AAA server to the BNG.
