Although It is still in alpha stage, I have a couple of reports about successfull RSTP implementations using it. As for MST - you need extra MSTP-aware hardware + specialized driver for that hardware. Alternatively you could modify the bridge subsystem code in kernel. In current state without modifications it has no support for the per-MST port states. -- With Best Regards, Vitalii Demianets
