Configuring Command-Line Access to the Router

Follow these steps to configure parameters that control access to the router.

ISDN as the Backup WAN Connection

This section tells how to configure ISDN to operate as a secondary, or backup,

WAN connection. With ISDN as a backup WAN connection, the router can

continue to operate if the main WAN connection is down. This configuration is

typically used on an ISDN WAN interface card that is installed in a Cisco router.

The router onboard WAN port is the primary, or main, WAN connection, and the

card WAN port is the secondary connection.
