I am trying to find a solution that does not require much scripting or customization.
Suggestion to run BMP is a fine suggestion. Another option is plain old BGP, setup iBGP+best-external (w/ add-path if you may receive >1 copy from local eBGP neighbours) from these boxes to a collector bgp, maybe with a prefix-list filter to send only this prefix. Then have the collector box raise an alert when it doesn't receive the route from one of them.
What about setting up a machine with exabgp installed, a iBGP session with the exabgp instance, and a small script parsing the updates received by exabgp to raise an alarm whenever $CONDITION is met ? https://github.com/Exa-Networks/exabgp Best, Paul
