LINUX failover between two default gateways



At some point hitherto, Derek Atkins hath spake thusly:
> You need to use dynamic routing on the client.  Look at gated.

That's an option, but also many Cisco products have failover
capabilities built into them.  IOW you can link them together, and the
secondary will automatically take over for the primary if it fails.
The IP of the gateway will float between them, and generally they'll
each have their own IP as well.

IMO this is the better way to solve the problem, because you don't
have to worry about (re)configuring dozens or hundreds of clients
correctly to deal with the redundancy.  Just point them all at your
one gateway IP, and let the routers do the rest.
