I was commenting on the special case of tagged/non-tagged frames on the same wire at the same time, and how that case is currently handled. My observation is that a bridge forwards packets based on rules (or VLAN tags) at layer-2. I don't see a difference if this happens on a physical wire, or inside the kernel drivers/protocol stacks. I have several goals (related to VLANs and FreeBSD) and starting an argument is definitely not one of them. Its not my intent to question your expertise, either as the code's architect, or in general. I'm working towards solid features in FreeBSD that I can use to simplify my production network environment. > > I believe it appropriate to make the lower protocol layers on FreeBSD > > comply with the specification for a bridge. > > I do not, unless bridging is actually configured. I see an administrative advantage to having your configuration be similar on all bridges or hosts that understand tagged frames. That's the motivation for my comments. Its entirely possible that I've missed something incredibly important here. Do you have some technical or philosopical reason to deviate from the advise of the published standard? - Steve -- C.
