Dual-Stack Lite is a solution to offer both IPv4 and IPv6
connectivity to customers that are addressed only with an IPv6
prefix.  Dual-Stack Lite requires pre-configuration of the Dual-Stack
Lite Address Family Transition Router (AFTR) tunnel information on
the Basic Bridging BroadBand (B4) element.  In many networks, the
customer profile information may be stored in Authentication,
Authorization, and Accounting (AAA) servers, while client
configurations are mainly provided through the Dynamic Host
Configuration Protocol (DHCP).  This document specifies a new Remote
Authentication Dial-In User Service (RADIUS) attribute to carry the
Dual-Stack Lite AFTR tunnel name; the RADIUS attribute is defined
based on the equivalent DHCPv6 OPTION_AFTR_NAME option.  This RADIUS
attribute is meant to be used between the RADIUS server and the
Network Access Server (NAS); it is not intended to be used directly
between the B4 element and the RADIUS server.  [STANDARDS-TRACK]
