Hi,

I was wondering if if_bridge had been taught how to speak multiple instance spanning tree?

Not yet. I havnt started it yet and I do not know of anyone else working
on it.

While playing with if_bridge today and a pair of Dell PowerConnect 5324's (with the recent upgrade to MSTP) I noticed that it did not seem to be possible to enable STP on if_vlan bridge members. This would seem to be correct as transmitting STP frames tagged with VLAN_ID would seem to break the spec and fall into the realm of cisco PVST. However should if_bridge be taught that the vlandev should be used for collection and transmission spanning tree in this scenario or should if_vlan be taught to copy untagged [R]STP frames onto the vlan interface?
