Dynamic route backup configuration example 4
Network requirements
As shown in Figure 61, Router A and Router B are connected through an FR network. They are also
connected through an ISDN switched network, enabling them to call each other. The telephone
number of Router A is 660330, and that of Router B is 660220.
Use Router A as the master device of a dynamic route backup group to monitor three network
segments 10.0.0.1/8, 11.0.0.1/8, and 12.0.0.1/8, which are all connected to Router B.
The FR link functions as the primary link between Router A and Router B. When the routes to all the
three network segments become invalid, Router A automatically establishes an ISDN BRI link to
Router B.
