Configuring Auto-Dial; Configuring Dynamic Route Backup Through Ddr - HP MSR Router Series Wan Access Configuration Manual

Step
3. Configure the interface to
accept incoming calls from
the specified calling number
or to call back to the 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 certain intervals. The established connection does not
disconnect due to timeout of the idle-timeout timer 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.
To use this feature, you must create a dynamic route backup group and define a network to be monitored.
When a dialup interface is assigned to the dynamic route backup group, the system monitors the route
by using the following process:
1. Whenever there is a route update for the monitored network, the system checks whether a
minimum of one valid route exists to the monitored network.

By default, auto-dial is disabled.
To configure an interface to place
calls to a single site, use the dialer
number or dialer route command
to specify the dial string to reach
the site. To configure an interface
to place calls to multiple sites, use
the dialer route command
multiple times to specify the dial
strings to reach these sites.
The autodial keyword must be
specified.
The default setting is 300
seconds.
