Hi Justin It makes perfectly sense to me but I am wondering if I would create loop as the trafic could comme back to the different path ports... (and as well for the Mac learning as you already mentioned)
Is there any specific commands to avoid both Mac learning and deny the traffic to come back from any port from the four bridge to the others bridges?
