Abstract
This document specifies the operation of RADIUS (Remote
Authentication Dial In User Service) when run over IPv6 as well as
the RADIUS attributes used to support IPv6 network access.
1. Introduction
This document specifies the operation of RADIUS [4]-[8] over IPv6
[13] as well as the RADIUS attributes used to support IPv6 network
access.
Note that a NAS sending a RADIUS Access-Request may not know a-priori
whether the host will be using IPv4, IPv6, or both. For example,
within PPP, IPv6CP [11] occurs after LCP, so that address assignment
will not occur until after RADIUS authentication and authorization
has completed.
Therefore it is presumed that the IPv6 attributes described in this
document MAY be sent along with IPv4-related attributes within the
same RADIUS message and that the NAS will decide which attributes to
use. The NAS SHOULD only allocate addresses and prefixes that the
client can actually use, however. For example, there is no need for
