Re: OT - BGP Problem

I have seen an IPSLA HTTP track run on the peering router that executes EEM
script to shutdown neighbor or physical interface when IPSLA starts
receiving timeouts and track is down. Only thing I don't like about this
approach is the logic and state becomes somewhat reliant on the site being
tracked. We used google.com because we would know pretty quick if that site
went down ;)
