You can probably find good sources of informations around on the net. Cisco comes immediately to my mind, 3Com and redbooks.com are also very likely to have. I'd also check ethereal sources, where packet-bpdu.c includes most of what you need to start interpreting packets you receive, and send new ones (well, you also need llcsaps.h and oui.h). Speaking of 802.1G (BCP) you should look at RFC2878... wait, checking on that again, I just found out that this is THE document for bridging, so start from that ;-) Also, RFC 1638 documents the old STP protocol. Even though I could find nothing more in RFCs, a quick tcpdump confirmed that most STP involves broadcasts to 01-80-c2-00-00-00. > I'd probably go for the Cisco defaults.

Ok. Please keep me updated. Bye, Andrea -- 0 and 1. Now what could be so hard about that?
