I had faced such situation once: I had multihomed host that was running Apache daemon that was announced via two DNS names that were corresponding to two different IPs, going via two different providers. When the first provider's link goes down, the second provider is still alive, and when both providers are alive, the traffic is balanced via DNS round-robin alias. Do you see some better way to do it via CARP, RIP, something different? I am still interested in other possibilities. Thank you! -- Eygene
