Configuring WAN interfaces
3. Define a track list consisting of all four object trackers, and configure it so that if all object
trackers are up, the track list is up, and if two or less of the object trackers are up, the track
list is down.
4. Register the WAN Fast Ethernet interface with the track list.
5. Define the serial 2/1:1 as a backup interface for the WAN Fast Ethernet interface.
Thus, when the track list is down the Serial interface will be up, until the track list is up again.
Note that RTR packets continue to be sent over the PPPoE interface as long as the PPP-IPCP
connection status is up.
Configuration example
! Define four RTRs to probe the four entrances to the Main Offices.
! Configure each one to run immediately and forever.
