RADIUS Attributes for Address plus Port (A+P) based Softwire Mechanisms
                   draft-ietf-softwire-map-radius-17

Abstract

   IPv4-over-IPv6 transition mechanisms provide IPv4 connectivity
   services over IPv6 native networks during the IPv4/IPv6 co-existence
   period.  DHCPv6 options have been defined for configuring clients for
   Lightweight 4over6, Mapping of Address and Port with Encapsulation,
   and Mapping of Address and Port using Translation unicast softwire
   mechanisms, and also multicast softwires.  However, in many networks,
   configuration information is stored in an Authentication,
   Authorization, and Accounting server which utilizes the RADIUS
   protocol to provide centralized management for users.  When a new
   transition mechanism is developed, new RADIUS attributes need to be
   defined correspondingly.

   This document defines three new RADIUS attributes to carry Address
   plus Port based softwire configuration parameters from an
   Authentication, Authorization, and Accounting server to a Broadband
   Network Gateway.  Both unicast and multicast attributes are covered.
