Configuring the Connecting Router

The Cisco 200 for Windows 95 can communicate with any Cisco Systems router that supports ISDN. This chapter contains 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, see the Cisco Connection Documentation, CiscoPro Solutions CD; the Cisco Connection Documentation, Enterprise Series CD; or the printed Cisco router documentation.

Guidelines

The following are general guidelines for configuring Cisco routers to communicate with the Cisco 200 for Windows 95:

Configure the interface encapsulation as Point-to-Point Protocol (PPP) and PPP multilink.
When using dial-on-demand routing, configure the 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 1-1 illustrates the authentication configuration for the connecting router.

Sample Router Configurations

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

Note The telephone numbers and service profile identifiers (SPIDs) given are examples only. The format of your ISDN telephone numbers and SPIDs might vary. For more information, contact your ISDN service provider (telephone company).

Cisco 2503 Using NI1 with Call Forward Busy

The following example illustrates a connecting router configuration using PPP multilink with PPP callback and the NI1 ISDN protocol. This example also includes Challenge Handshake Authentication Protocol (CHAP) and assumes that the NI1 switch is configured for call forward busy (CFB or hunt) and that the connecting router is also on an NI1 switch.
