IP SLA failover

Can someone provide me with a config example of how I could configure IP SLA failover on the switch if10.153.0.2 goes down to faill back on 10.153.2.2? I currently have static route from anything to 10.153.0.2. I have attached an image of my network. Thank you

If 10.153.0.2 should go down, then the route using that next-hop will be removed from the routing table.

So I would create two static routes using a higher AD on the route using 10.153.2.2 as the next-hop.

ip route 0.0.0.0 0.0.0.0 10.153.0.2
ip route 0.0.0.0 0.0.0.0 10.153.2.2 150

Which means when both links are up, traffic will use the 10.153.0.2 route. If that link fails, then that route will be removed and all traffic will then take the 10.153.2.2 route.

I see, so i dont have to create route-maps for this? as long as I have secondary route with higher AD i should be OK
