Using IP and IPX Unnumbered Protocols for PPP Connections

The RADIUS client supports IP and Internetwork Packet Exchange (IPX)

unnumbered interfaces, meaning that the circuit’s interface address is 0.0.0.0. All

remote users that dial in to the same slot on the client receive the same

unnumbered protocol configuration.

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 authentication 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. See Configuring IP, ARP, RARP, RIP, and

OSPF Services or Configuring IPX Services for more information about triggered

updates.

Using RADIUS with a Dial Service

To use RADIUS authentication with a dial service, you must configure at least one

of the three Nortel Networks dial services: dial-on-demand, dial backup, or

bandwidth-on-demand. The dial service enables the router to activate a dial-up

connection when it receives an incoming call. For information about configuring a

dial service, see Configuring Dial Services.

Note:

Unlike the circuit’s address, the RADIUS client’s address is a numbered

address.
