1.6.10 Example for Configuring Association Between Interface
Backup and Routing on an ISDN Network
This section describes how to configure association between interface backup and routing.
Networking Requirements
As shown in
connects to the IP network through GE1/0/0. The link between GE1/0/0 and the IP network is
used as the primary link. The link between PRI1/0/0:15 and the ISDN is used as the backup link.
To prevent service interruption due to the primary link fault, configure interface backup and
routing on RouterA to detect the route status on the primary link. When the routing entry of the
primary link is deleted or becomes inactive, the backup interface PRI1/0/0:15 starts to transmit
traffic. This improves network reliability.
