Hi Nelson,
I think, for failover below would wotk just fine
1. Configure the 2 static routes with difference in AD values to serve as primary /seconday
2. Create Track & IP SLA ......# this will check if the ISP gateway IP is reachable or not, track will go down once the ISP gatewat becomes unreachable #
3. Configure the Static route with Track as below:
ip route 0.0.0.0 0.0.0.0 <next-hop-ip-address> track 1
# this route will stay in routing table as long as the Track status is up, means ISP gateway is reachable, if the Track goes down, route will be removed from the routing table & then routing will be done fall back to alternate available routes
