IP SLA
Automatic Failover to Backup Link
First we'll create a IP SLA tracker to ping an internet address.
-Note: Timeout is in milliseconds. Frequency is in seconds.
ip sla 1 icmp-echo 8.8.8.8 timeout 500 frequency 30 ip sla schedule 1 start-time now life forever track 1 rtr 1 reachability
Next we'll configure the default route, and associate it with the tracker we just created.
ip route 0.0.0.0 0.0.0.0 1.1.1.1 track 1
Now we'll add our backup route.
ip route 0.0.0.0 0.0.0.0 1.1.1.2 10
