Configuring a callback server by using bundle DDR

Step
1. Enter system view.
2. Enter dialer interface view.
3. Configure the interface to
accept incoming calls from
the specified calling number
or to call back to
specified calling number.

Configuring auto-dial

Auto-dial can be used with traditional DDR or bundle DDR. With auto-dial enabled, DDR
automatically dials a connection to the remote end upon router startup without requiring a triggering
packet. If the connection cannot be established, it will retry at the auto-dial interval. The established
connection does not disconnect due to the idle-timeout timer expiration as it would in
packet-triggered DDR.
To configure auto-dial:
Step
1. Enter system view.
2. Enter dialup interface view.
3. Configure one or multiple
destination addresses and
dial strings that can be
auto-dialed.
4. (Optional.) Set the auto-dial
interval.

Configuring dynamic route backup through DDR

The dynamic route backup feature creates a dialup connection to a network when no valid route on
the primary link is available to the network. This feature is mainly used to back up dynamic routes. It
can also back up static routes and direct routes.
