WAN interfaces
In the previous typical application (see
interface on page 293), the backup interface command is used to specify a backup
interface. This typical application illustrates an alternative to the backup interface
command, using policy-based routing (PBR) which configures a routing scheme for specified

Thus, when the track list is down the Loopback 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.
! Define four object trackers to track the four RTRs.

track 3 rtr 3

! Define a track list consisting of the four object trackers.
! Define a threshold calculation such that if all four object trackers
! are up, the list is up, and if 2 or less are up, the list is down.
