While we're on this topic... I'm facing a similar situation, where a bunch of publicly addressable hosts have a primary default route and a secondary. I was wondering if there is some reliable way of doing this kind of failover, or even if there is a ready-made solution out there. My concern with doing this myself is important scenarios I might be missing. For example, routers that drop pings under congestion. Or indeed if both my routers end up in an unreachable state, to not end up with an empty route table. I'm not on FreeBSD, but Linux myself. And I know Linux can do failover using the neighbour table and multiple routes with metrics. But all of this appears to be undocumented voodoo. What's really the proper way of doing this?
