Figure 55 Relationships among physical interfaces, dialer interfaces, and call destinations
Bundle DDR is simpler and more flexible than traditional DDR. Bundle DDR separates physical interface
configuration and logical configuration for calls and allows one-to-many bindings between dial services
and physical interfaces. A physical interface can serve multiple dial services.

DDR types

Depending on how DDR calls are triggered, DDR includes packet-triggered DDR, auto-dial DDR, and
route-triggered DDR.
Packet-triggered DDR
You can define packets on a dialup interface as interesting and uninteresting by configuring access
control rules. Only interesting packets trigger outgoing calls and reset the link idle-timeout timer.
Before a dialup connection is established, uninteresting packets will be dropped. After a dialup
connection is established, uninteresting packets can be forwarded. When the link idle-timeout timer
expires, DDR disconnects the connection.
