Yes, they'll have to go through the root-bridge. STP will create a tree by shutting down ports causing loops. That's how STP works. It's all about avoiding loops... Not following the shortest path is not very important for a layer two device. Creating a loop in the topology and bringing the network down because of it, is. > In my case there's a straight connection between bridge1 > and bridge2 too, so that they don't have to communicate through > root-bridge. Yes, but that also can create a loop and according to STP must be eliminated. Perhaps you can use some inventive IP addressing scheme, to force direct communication... some ifconfig option(the edge option?) to force forwarding... a tunnel... or some other weirdness(TM) ;) Nikos
