Primary route takes IP traffic via fiber links from Router A to Router B and finally to Router C. There is also a Wireless Radio link between Router A and Router C and is configured as the backup route if the primary path goes down. If the fiber link between Router A and Router B goes down my backup route works perfectly. But here is my problem if the fiber link between Router B and C goes down I end up with a routing loop between Router A and Router B because Router A sees that the first fiber link as still working/being good. Is there a “link” based command/rule that I can configure that would ping through the primary link and then if say the primary link went down for more than 15 sec switch over to the secondary link? And then if the primary link comes back up switch back automatically? I am open to any suggestions it doesn’t necessarily have to be link based; it is just the first thing I thought of.
I tired the commands you posted with no success. Maybe I’m not using them correctly? I put in the IP address of router C instead of 188.8.131.52 and put in the interface of the fiber link instead of FastEhternet8, which was the correct thing to do???
Also from the link you posted about the SLA commands it appears SLA is a “monitoring/measuring” tool, so is SLA the correct command to be used in this scenario to allow a backup link to work?

This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
