redundant network problem
Hi, I have a requirement in my new project, where each system shall have two Ethernet card interfaces(system means hardware devices, servers, clients in other words any device or host used in the project). The IP address of each interface will be of different networks. Bcoz if one of the Ethernet interface is down, respective system should take the other interface that is connected to different network.
In one of the forums, I have understand NIC bonding, but that works fine when all the systems are in the same network, but I want single to switch between networks.
I have seen for Multi-homing but that requires the BGP enabled router.. which is so costly solution.
Can anyone give me some solution in Linux to solve my problem, something like tools, application or linux inbuilt configuration/setting to be enabled.
Please help me it is very urgent to be solved.
Thanks in advance..
