Example ISDN Configuration
For your reference, Table 9 shows an example configuration for a Catalyst 3100 switch with a router
card installed, and a Cisco router using IP over ISDN. In the example, the router card (branch1) is
at a remote site and the target router (main1) is at a central site.

Configure a static route to allow connection to the target router's LAN. Enter the IP
address and subnet mask of the target router's LAN interface, and the IP address of the
target router's BRI port:
Router (config)# ip route targetrouter_ipnetwork subnetmask
targetBRIport_ipaddress
Enter the exit command to exit global configuration mode.
Enter the copy running-config startup-config command to save the configuration to
NVRAM.
