Configuring Dialer Watch

Dialer watch is a feature that integrates backup dialing with routing capabilities and
provides reliable connectivity without relying on "interesting" packets to trigger
outgoing ISDN connections. With dialer watch, the Services Router monitors the
existence of a specified route and if the route fails, the dialer interface initiates the
ISDN connection as a backup connection.
To configure dialer watch, perform the steps in the following sections to configure
the dialer interface and the physical ISDN interface:
