Connecting Routers and the Cisco 200

The Cisco 200 for DOS, Windows 3.1, and Windows for Workgroups 3.11 can communicate with any Cisco router that supports ISDN. This appendix provides guidelines for configuring the connecting router and sample configurations.

Before you install and configure your Cisco 200, you should verify that the connecting router is properly installed and configured. For more information on router installation and configuration, refer to the Cisco Connection Documentation CD-ROMs or the printed Cisco router documentation.

Guidelines

The following are general guidelines for configuring Cisco routers to communicate with the Cisco 200:

Configure the interface encapsulation as PPP and PPP multilink.
When using dial-on-demand routing, configure the Challenge Handshake Authentication Protocol (CHAP) authentication and dialer maps.
The router "hostname" must be identical to the Cisco 200 "connecting router name."
The router "username" must be identical to the Cisco 200 "local system name."
The password configured for the router "username" must match the password configured on the Cisco 200.

Figure A-1 illustrates the authentication configuration for the connecting router.

Sample Router Configurations

The following sections provide sample configurations for a Cisco 2503 router. The configurations of other Cisco Access and Cisco Enterprise routers will be similar.

Cisco 2503 Using NI1

The following example illustrates a connecting router configuration using PPP multilink with PPP callback and the NI1 ISDN protocol:
