I have four switches node arranged in a ring topology; I am using RSTP or STP.
I learned the classic three switches ring topology. Is the four switches topology using the same method as three switches to decide the port state? If so, at what step and what is the different between RSTP and STP? How can I know what state the switch port is in besides testing it?
