I'm looking at linking two networks with a long range Ethernet bridge. I know I can connect my two networks with a router, but my problem is how will my computers know where to send packets if I don't add the route manually? I COULD add them manually, but it seems like a hassle. I have very very limited knowledge of RIP (I know it has something to do with routing), but I don't know how to use it.
edit: My vision for the network would be the 2 networks (which are currently independent home networks), connected by a microwave Ethernet link. I assumed i'd need a router on one end of the bridge, to handle communication between the 2 networks.
