How RADIUS Relay Server Works

E Series router
RADIUS relay is supported on all E Series routers.
For information about the modules supported on E Series routers:
See the ERX Module Guide for modules supported on ERX7xx models, ERX14xx models,
and the ERX310 Broadband Services Router.
See the E120 and E320 Module Guide for modules supported on the E120 and E320
Broadband Services Routers.
For more information about RADIUS relay server, see the following resources:
IEEE 802.1x-2001—Port-Based Network Access Control
RFC 2869—RADIUS Extensions (June 2000
RFC 2284—PPP Extensible Authentication Protocol (EAP) (March 1998)
RFC 3539—Authentication, Authorization and Accounting (AAA) Transport Profile
(June 2003)
When a wireless subscriber starts a session, the WAP encapsulates EAP attributes into
a RADIUS Access-Request message and sends the request to the E Series router, which
the WAP views as the RADIUS server. The encapsulated message uses the RADIUS
EAP-Message (79) attribute. The RADIUS relay server does not process any of the EAP
attributes in the RADIUS Access-Request message; the encrypted message is simply
passed through the router to the actual RADIUS server. The RADIUS server must be EAP
aware.
