Description

This command is used to configure an interface as a backup DDR link using a watch list. The group-number identifies the watch list that triggers calls on this interface; the interface is brought up if the router doesn’t have any routes to the networks listed in the watch list. A watch list is created by the dialer watch-list command; the interface must have a dialer map that corresponds exactly to the networks listed in that command.
