gateways redundancy(of same subnet/interface) for one network

[sunilkrchopra@gmail.com]

Hi
i am looking for gateway redundancy solution in Linux machine so that if primary Gateways goes down the network shall be reachable to secondary or vice versa without using external routers. Both gateways lies in same subnet as of linux machine. There shall be same eth0 interface for both gateways.

Each gateway system is router.

i do not have expertise in scripting ip tables etc. so pls suggest some solution of auto redundancy for both gateways.
