Creating a dynamic route backup group
You can create a dynamic route backup group using one of the following methods:
Creating multiple dynamic route backup groups, each of which monitors a network segment.
The backup link will be activated when the route to a network segment being monitored becomes invalid. Each dynamic route backup group can establish or tear down a link through a dialup interface.
Creating a dynamic route backup group to monitor multiple network segments.
The backup link will be activated when the routes to all the network segments being monitored becomes invalid. When establishing the backup link, the dynamic route backup group checks for dialup interfaces configured with the dialer route command and tries to establish the backup link on the first such interface. Only one backup link is established.
