Configuration example for dynamic route backup for multiple
networks
Network requirements
As shown in
They are also connected through an ISDN switched network, enabling them to call each other by using
traditional DDR. The telephone number of Router A is 660330, and that of Router B is 660220.
Configure dynamic route backup on Router A to monitor the networks 10.0.0.1/8, 1 1.0.0.1/8, and
12.0.0.1/8, which are all connected to Router B.
The PPP link functions as the primary link between Router A and Router B. When the routes to all the three
networks become invalid, Router A automatically initiates a backup link through ISDN to Router B.
Figure 70 Network diagram
This network diagram only illustrates a simple application where a dynamic route backup group is used
to monitor multiple subnets. In actual use, the monitored networks can be connected to multiple devices.
Configuration procedure
1. Configure Router A:
# Create dialer group 1 and configure a dial rule for it.
<RouterA> system-view
[RouterA] dialer-group 1 rule ip permit
# Create a dynamic route backup group to monitor three networks.
[RouterA] standby routing-group 1 rule ip 10.0.0.0 255.0.0.0
[RouterA] standby routing-group 1 rule 11.0.0.0 255.0.0.0
[RouterA] standby routing-group 1 rule ip 12.0.0.0 255.0.0.0
# Bundle timeslots on the CE1 interface into a PRI group.
[RouterA] controller e1 2/3/1
[RouterA-E1 2/3/1] pri-set
Figure 70, Router A and Router B are directly connected through serial interfaces running PPP.
