Definetly between routers would be using BGP. But, I heard at an apache conference somebody was doing something where the machine would send a keepalive to the directly connected Cisco router, and if the router didn't receive the keepalive signal, BGP would re-route the traffic to the other host. Both hosts are on different ISP, but have the same IP address. Traffic is routed from the requester to the closest logical server. I think UltraDNS does this with their DNS servers as well. Anyway, I don't know what the host uses to send the keepalive to the Cisco router, or even how to configure the BGP to make it work. I was wondering if somebody on the list has set up the same configuration on a couple of fault tolerant FreeBSD boxes.
