WebRapid Spanning Tree Protocol (RSTP) is the second STP type. It is a fast converged version of Spanning Tree Protocol as its name implies. RSTP bypass the Blocking State and Listenning State of STP, and provide Forwarding State in 15 Seconds. So, the convergence time is lower than STP. In some cases, Rapid Spanning Tree Protocol is similar to STP. WebFeb 20, 2024 · In my opinion RSTP is not the best choice, MRP or REP can help in this type of ring topology, but 45 switch is very a lot number on the same ring. The limitation of REP is 25 and MRP is 50 I guess. However I suggest you to divide the topology in more rings. I'm really interested if anyone can suggest anything other. Helpful Share Reply
