what about "unexpected network behaviour"? ;-) Tunneling STP BPDUs means there will only one STP root (per VLAN in most cases) in your VPLS structure (be a "full one", be one part of a hierarchical one). Depending on your topology this might induce (at a first glance) "strange frame forwarding paths", including "local site traffic" going through a "remote site STP root". Thinking of other types of PDUs (like VTP) you may even encounter far worse things like a remote site's VTP server (with high rev number) overwriting remote sites' ones. For some discussion of this stuff see http://www.ernw.de/content/e7/e181/e972/erey_security_ethernet_services_ger.pdf thanks, Enno > > Anyway maybe some of you have expirience with BPDUs tunneling > via VPLS ?
