Dynamic route backup for traditional DDR configuration
example
Network requirements
As shown in
running PPP. They can also call each other by using traditional DDR. The telephone number of
Router B is 8810052.
Enable dynamic route backup on Router A to monitor network segment 40.0.0.0/8 on Router B.
The PPP link acts as the primary link between Router A and Router B. When there are no valid
routes to the 40.0.0.0/8 network segment, Router A automatically creates an ISDN BRI link.
Figure 66, Router A and Router B are directly connected through their serial interfaces
