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.
