I created a vlan 0 interface using the vlan package and vconfig under linux . I'm just wanting to set the 8021p tags not segregate traffic. However I noticed that untagged traffic is is not being allowed thru the interface that I configured( in this case eth0.0). This seems like a bug in the VLAN module since VLAN 0 is a reserved id used to indicate priority tagged traffic so I would expect it to accept traffic tagged with VLAN 0 and untagged traffic. In any case I'm trying to see if I can create a bridge with eth0.0 interface associated with the bridge and then use ebtables to add a VLAN priority tag to an incoming untagged packet so the packet will get processed. I also want to strip off the VLAN 0 traffic with priority 0 on outgoing traffic. Based on my research this isn't possible and I would just like someone to confirm. Thanks Mark
