Configuring RADIUS

1-12

308640-14.00 Rev 00

The unnumbered circuit interface eliminates the need for a unique circuit

configuration for each remote user in a network. Therefore, an unnumbered circuit

interface reduces the configuration effort and the number of IP addresses that you

use for a large network. The client can activate any available circuit for an

incoming call because there is no specific address assigned to the circuit.

When you configure accounting for a router slot, Site Manager automatically

configures the dial-up circuits required for the client to accept calls from the

remote user. You are responsible for configuring only the unnumbered circuit

interfaces. If you use an FTP Telnet session, this configuration is unnecessary.

In addition to configuring unnumbered circuit interfaces, we recommend that you

enable IP or IPX triggered updates for the RADIUS client. The client uses

triggered updates to provide its local area network (LAN) with routing

information from the remote router. Refer to Configuring IP, ARP, RARP, RIP, and

OSPF Services or Configuring IPX Services for more information about triggered

updates.

Using Dial VPN Services with Multilink PPP Accounting

The Dial VPN services (DVS) feature reports multilink PPP (point-to-point

protocol) usage to the RADIUS accounting server. Nortel Networks enables this

feature by default.

Prior to BayRS Version 14.00, DVS only reported one session per multilink

bundle to the RADIUS accounting server. Now, DVS reports one session per link,

so that as links are added to or removed from a multilink bundle, the RADIUS

accounting server at the customer site receives accounting messages.

This new behavior resembles the operation of a RAS (remote access server) in

local (non-DVS) mode and allows customers to perform usage-based billing of

multilink PPP sessions.

In addition, the new multilink PPP accounting feature:

• Does not report the Termination-Cause attribute in the accounting STOP

message.

• Ensures uniqueness by having the gateway locally generate the NAS-Port,

Session-Id, and Multi-Session-Id attributes.
