(Sorry, forgot to CC the list). Hi Geoff, thank you for your answer. Geoff Wiener <gwiener@xxxxxxxxxxxxxxx> wrote: I've had this very issue. I know that 2.6.24-16 allows PVST BPDUs to cross the bridge. Linux won't speak Cisco PVST+ but it will pass the BPDU's so that Cisco devices on both sides can communicate about the link state. But isn't that part of the problem? Imagine this situation, I have: 1 physical interface - eth0; 2 virtual lan interfaces - vlan15 and vlan16. 1 bridge - br0 - bridging vlan15 and vlan16. The reason I have to filter the PVST+ BPDUs out (with ebtables) is that, when the Cisco switch sees a BDPU on VLAN 15 that belonged originally to VLAN 16, it will assume a loop was detected and shut down the switch port where eth0 is connected. If Linux could convert the VLAN 15 BDPU to a VLAN 16 BDPU, before sending it to VLAN 16, I believe the problem would be solved.
