Hi, I'm planning to set up OpenWRT-based routers at three sites, and I'd like to bridge together all thee local ethernets. All three sites are behind typical residential DSL links, so I'd like to have a full mesh: A talking to B and C, B to A and C, and C to A and B. I think I have figured out the iptables rules for having a local DHCP server on each end, and appropriate default gateway settings and such, but I'm afraid that the bridging itself might pose a problem. If I just connect all three together in a bridge, unicast packets will be handled without problem, as each bridge will know where each MAC lives (local, remate A, or remote B). However, a multicast or broadcast packet will be sent from the local network out to each of the two remote networks, where it will be re-transmitted to the other node, and so on ad infinitum. If I enable Spanning Tree Protocol on the bridges, this problem is avoided, but all traffic between A and C will go via B (if B is established as the STP root node), even though there is a direct link between A and C. I could change to a routed configuration, but that would make certain applications more cumbersome. Is anybody running such a configuration?
