After a quick search on google for "spanning tree" and "BPDU", here are some usefull links: http://www.ece.wpi.edu/courses/ee535/hwk96/hwk3cd96/sef/sef.html http://www.synapse.de/ban/HTML/P_LAYER2/Eng/P_lay119.html http://www.ethereal.com/lists/ethereal-dev/199910/msg00070.html http://www.support.baynetworks.com/library/tpubs/html/router/soft1000/bridge /2950A-16.html Apparently there is an implementation in linux (look for the file net/bridge/br_stp_bpdu.c) and the "BRIDGE-STP-HOWTO" (http://www.ibiblio.org/pub/Linux/docs/HOWTO/other-formats/html_single/BRIDG E-STP-HOWTO.html) http://www.linuxhq.com/kernel/v2.3/patch/patch-2.3.47/linux_net_bridge_br_st p.c.html Patrick.
