RADIUS Option for DHCPv6 Relay Agent on the Broadband Access Servers
draft-ietf-dhc-dhcpv6-radius-opt-09
Abstract
The DHCPv6 RADIUS option provides a mechanism to exchange
authorization and identification information between the DHCPv6 relay
agent and the DHCPv6 server. This mechanism is meant for the
centralized DHCPv6 server to select the right configuration for the
requesting DHCPv6 client based on the authorization information
received from the RADIUS server, which is not co-located with the
DHCPv6 server. The Network Access Server (NAS) acts as DHCPv6 relay
agent and RADIUS client simultaneously in this document.

Internet-Draft DHCPv6 RADIUS Option February 2013
1. Introduction
DHCPv6 provides a mechanism that allows the server to assign or
delegate both stateful and stateless configuration parameters to the
clients. The stateful configuration parameters include IPv6 address
[RFC3315], IPv6 prefix [RFC3633], etc. The stateless configuration
parameters [RFC3736] include, for example, DNS [RFC3646], or a FQDN
of AFTR [RFC6334]. In the scenarios described in this document, the
DHCPv6 server is deployed in the central part of an ISP network.
RADIUS [RFC2865] is widely used as the centralized authentication,
authorization and user management mechanism for the service provision
in Broadband access network. [RFC3162], [RFC4818], [RFC6519] and
[I-D.ietf-radext-ipv6-access] specified attributes that support the
service provision for IPv6-only and IPv6-transition access. RADIUS
server authorizes the Network Access Server (NAS) to assign an IPv6
address or prefix from the indicated pool, or to assign an IPv6
address or prefix with an explicitly indicated value, and other
