Steps

1. Create the monitor
   
   
   
   (config)# ip sla monitor <#>
   
   (config-sla-monitor)# type <type> <options>
   
    
2. Schedule the probe
   
   
   (config)# ip sla monitor schedule <#> start-time <start> life <life>
   
      
3. Configure the track object
    
   (config)# track <#> rtr <#> reachability
   
      
4. Apply the tracking in a route-map
