Hello. If you read faq at http://bridge.sourceforge.net/faq.html you know: " * I keep getting the message 'retransmitting tcn bpdu'! It means that your linux bridge is retransmitting a Topology Change Notification Bridge Protocol Data Unit (so now you know what the letters are for :-). Seriously, there is probably another switch (or linux bridge) nearby that isn't complying to the rules of the spanning tree protocol (which is what bridges speak). In each bridged local area network, there is one 'master bridge', which is also called the root bridge. You can find out which bridge this is using brctl. ... There are a number of things you can do: + Find out which bridge is the root bridge, find out where it is located, and what internetworking software it runs. Please report this info to the mailing list (or to me directly), so that I can keep a blacklist. + Force the linux bridge to be the root bridge. See what the priority of the current root bridge is, and use the brctl 'setbridgeprio' command to set the priority of the linux bridge to 1 lower. (The bridge with the lowest priority always becomes the root bridge.) + Disable the spanning tree protocol on your linux bridge altogether. In this case, watch out for bridging loops! If you have loops in your topology, and if no bridge in the loop is running the spanning tree protocol, mayhem will come your way, as packets will be forwarded forever. Don't Do This(TM). "
