Hi Amusil,
You could definitely ping two ip addresses and if anyone fails you could remove the tracked route. Here is what you have to do:
1. Create two IP SLA probes to monitor the two ip address. Let us say these probes are are IP SLA 1 and IP SLA 2.
2. Create two track objects which would track these two IP SLA objects. Let us say you created two track objects 1 and 2.
3. Create a third track object (track 3) and make it as a list with AND operation. Add track 1 and track 2 to this track 3 as objects. Now what this will do is if both the track objects 1 and 2 are up then only track 3 would be up but if any of the track objects (track 1 or track 2) goes down, this track 3 will go down. You could also use OR operation.
4. Use this third track object in tracking.
Here is a small example comfig:
!
ip sla 1
icmp-echo 192.168.1.1
ip sla schedule 1 life forever start-time now
ip sla 2
icmp-echo 192.168.1.2
ip sla schedule 2 life forever start-time now
!
track 1 rtr 1
!
track 2 rtr 2
!
track 3 list boolean and
object 1
object 2
!
ip route 0.0.0.0 0.0.0.0 172.16.1.1 track 3
==============================================
Here you could see if track 2 would go down track 3 would also go down:
*Feb 22 15:09:11 UTC: %TRACKING-5-STATE: 2 rtr 2 state Up->Down
*Feb 22 15:09:12 UTC: %TRACKING-5-STATE: 3 list boolean and Up->Down
I hope this helps you.
Cheers,
Ruchir
