Yes. If you tunnel, you cannot receive tunnel MACs in the lan side (so
customer itself cannot run L2PT over your service, or otherwise use such
I think it's security measure, to avoid some customer of customer from sending
tunneled BPDU, which would be translated by your kit on far-end to legit BPDU.
Even though if original source port had BPDUfilter or BPDUguard.
