Using IP and IPX Unnumbered Protocols for PPP Connections
The RADIUS client supports only IP and IPX unnumbered interfaces, which
means 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.
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 Services or
Configuring IPX Services for more information about triggered updates.
Note:
Unlike the circuit’s address, the RADIUS client’s address is a numbered
address.
