For easy reading: http://www.karthaus.nl/r/ Hi, We used to have 1 single ip range (1.1.1.0/24) that had one uplink to a switch of the colocation provider. Recently we got a second range 2.2.2.0/24 and a redundant uplink directly on two routers. But our switch does not have spanning tree protocol support so we cannot use them redundantly. We have set up the switch to have a vlan for both networks like in this picture: http://www.karthaus.nl/r/r1.gif this way all hosts on the switch can use ips from either network. However if one of the routers fails, one of the ranges fails. This happens quite a lot but this whould not be a problem if we had spanning tree that whould allow us to use both uplinks for both networks. I would like to use a linux box to do this until we can get a switch that is capable of stp. I was thinking of something like this: http://www.karthaus.nl/r/r2.gif After reading the documentation on linux bridging and stp i'm convinced it's possible but i'm not at all sure exactly how to do this. The box that i want to use should probably have three NIC's, one for each routeruplink and one that connects to our switch. (see the picture). I'm guessing that i need to set up multiple bridges each containing a subset of the NIC eth0,eth1 and eth2. But this is where i'm confused. Can anyone show me how to set this up please?
