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 1 rtr 1

track 2 rtr 2
exit
track 3 rtr 3

track 4 rtr 4

! 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.

! Configure PPPoE encapsulation on interface WAN FastEthernet 10/2, and

Typical application – interface backup using policy-based routing
In the previous typical application (see Typical application – backup for the WAN FastEthernet
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
WAN interfaces
