BGP On Host

I wasn't sure if it was BGP or if it was something else. 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.
