Hello, we're in a remote area, fairly isolated on an island. We occasionally experience outages downlink on our ISPs who each have their own infrastructure. Neither will support BFD although it's not really a solution for this problem.
I'm looking to track 5 SLAs with 20/80 thresholds and then use the EEM to alter the route.
Since I'm not actually down between me and the neighbor (ISP), what would be the best approach? Should it be something in BGP router config? Like removing the neighbor remote maps? Or would it be a good idea to change path prepend and local preference on outbound and inbound route-maps for the primary ISP?
Or maybe I could have a route-map for backup ISP with lower permit that has no prefix-list filter, and the EEM inserts/removes the prefix-list?
Primary ISP is much faster, and backup ISP is only used in cases of failover so currently the local preference is lower on the backup ISP, and backup ISP is also path prepended 3 times, and all traffic is going through primary ISP.
