I have two 2851 routers connected to two carriers (for redundancy) running BGP. R1 (primary router) is connected via Fa0/1/0 to the Qwest router on site. I have it configured to track Fa0/1/0 and decrement if this interface goes down:

track 100 interface FastEthernet0/1/0 line-protocol
!
interface GigabitEthernet0/0
ip address 21.43.20.4 255.255.255.0
no ip redirects
duplex full
speed 100
standby 1 ip 21.43.20.1
standby 1 priority 105
standby 1 preempt
standby 1 track 100 decrement 10


But this will not work if the Qwest router stays up but it's WAN connection goes down. How can I configure this router to failover in this scenario.

This is from Cisco TAC:

"Regarding HSRP you need to change the track, now we will be pinging the default gateway, that way when you loose connectivity HSRP will failover to the secondary Router:

ip sla monitor 1
type echo protocol ipicmpecho 6.16.5.29 source 6.16.5.30
exit

ip sla monitor schedule 1 start-time now
track 123 rtr 1 reachability
exit


Then apply the track to the HSRP ( and remove the previous one ):

IE

interface GigabitEthernet0/0
no standby 1 track 100 decrement 10
standby 1 track 123 decrement 10
