We have around 100+ eBGP peers to customers. We use BGP for failover purposes on their assigned ranges. Obviously the timers for BGP can be a bit long so if their WAN goes down then failover can take a few minutes. This hasn't really caused us any problems but it would be nice to have a faster failover.
Has anyone noticed if adding BFD to multiple BGP peers to add much of a performance hit at all? This would be on ASR1002 routers but I would also probably want to add it to MX104 PE's as well.
thanks
