Currently have a BGP multihoming configuration to 2 different ISPs. BGP failover time seems to be taking between 3/4 mins. All BGP timers are currently set to defaults. Can anyone give me any advice on how to reduce the time it takes for BGP to failover onto the secondary eBGP peering when the primary eBGP peering stops forwarding traffic? I know we could possibly change the keepalive and holdtimes on the eBGP neighbors, but not sure this would be good practice.
Any recommendations or advice would be greatly appreciated.
