Hi all,
This may be OT but I am open to the idea of building a custom linux
router if need be ... We have an application that during 8am-5pm it
cannot fail. We want to use redundancy (not a cluster) should the main
machine fail, and on failure route everything to a backup perhaps on
another subnet. The big question is would we manually have to change
the routing rules? Or can a router detect the failure and re-route
automagically? I'm googling alot for routers and what I see is for
detecting internet failure, not so much just one machine on a subnet
failure.
To reroute everything to a different box upon failure would require
that every client monitor the router and know how to change. What you
need to do is have the backup router monitor the main. If the main
stops responding the backup needs to take over the master's IP etc.
