Auto-dial DDR
DDR automatically initiates a dialup 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 will not disconnect due to timeout of the idle-timeout timer.
Route-triggered DDR
You can configure networks to be monitored and then associate a dialup interface with the networks.
When no routes to the monitored networks exist, DDR creates a backup connection from the dialup
interface to forward traffic. After the backup link is activated, the system regularly checks the status of the
primary link. When the primary link recovers, the backup link is disconnected immediately or when the
timer expires, depending on your configuration.
