RADIUS Option for the DHCPv6 Relay Agent
Abstract
The DHCPv6 RADIUS option provides a mechanism to exchange
authorization and identification information between the DHCPv6 relay
agent and DHCPv6 server. This architecture assumes that the Network
Access Server (NAS) acts as both a DHCPv6 relay agent and RADIUS
client. When receiving messages from the DHCPv6 clients, the NAS
consults the RADIUS server and adds the RADIUS response when
forwarding the DHCPv6 client's messages to the DHCPv6 server. The
DHCPv6 server then uses that additional information to generate an
appropriate response to the DHCPv6 client's requests.

1. Introduction
DHCPv6 provides a mechanism that allows the server to assign or
delegate both stateful and stateless configuration parameters to
clients. The stateful configuration parameters include IPv6
addresses [RFC3315] and IPv6 prefixes [RFC3633]. The stateless
configuration parameters [RFC3736] include, for example, DNS
[RFC3646], or a Fully Qualified Domain Name (FQDN) of an Address
Family Transition Router (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 service provision in
a Broadband access network. [RFC3162], [RFC4818], [RFC6519], and
[RFC6911] specify the attributes that support the service provision

for IPv6-only and IPv6-transition access. The 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 to indicate other
