For information about configuring DHCP support on the E Series router, see "DHCP
Overview" on page 455.
For information about how to configure a RADIUS server, see your RADIUS server
documentation.

AAA Overview

Collectively, authentication, authorization, and accounting are referred to as AAA.
Each has an important but separate function.
Central management of AAA means the information is in a single, centralized, secure
database, which is much easier to administer than information distributed across
numerous devices.

Remote Access Platform Considerations

B-RAS services are supported on all E Series routers.
For information about the modules supported on E Series routers:

B-RAS Protocol Support

The E Series router supports the following protocols for B-RAS services:
DHCP proxy client and server
DHCP relay agent (Bridged IP only)
DHCP local server
DHCP external server
Authentication Determines who the user is, then determines whether that user
should be granted access to the network. The primary purpose is to prevent
intruders from networks. It uses a database of users and passwords.
Authorization Determines what the user is allowed to do by giving network
managers the ability to limit network services to different users.
Accounting Tracks what the user did and when they did it. You can use
accounting for an audit trail or for billing for connection time or resources used.
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 Juniper
