I don't know what type of devices you have but I do that on one of our
Proteon gateways.  The two subnets are normally joined by two of these IP
routers.  The networks are also joined together by bridges for all other
protocols.  If one of the routers fails, I shut the IP filtering off on the
bridges, and add the interface address of the broken gateway to the
good gateway on the same ethernet interface.  The bridges make the system
look like one ethernet and the gateway handles the routing for the IP
packets.
