RADIUS Attribute for Softwire Address plus Port based Mechanisms
draft-ietf-softwire-map-radius-13
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 an Authentication
Authorization and Accounting (AAA) server, while user configuration
information is mainly provided by the Broadband Network Gateway (BNG)
through the DHCPv6 protocol. This document defines two new Remote
Authentication Dial In User Service (RADIUS) attributes that carry CE
configuration information from an AAA server to BNG.
