Topology Changes in Spanning Tree Protocol (STP)

WebSpanning Tree Protocol (STP) topology changes affect all the switches in Layer 2 topology. When a switch detects a link change, it will send a Topology Change Notification (TCN) Bridge Protocol Data Unit (BPDU) out of its root port (RP) intended for the root switch. The upstream switch receiving the TCN will send an acknowledgment and forward ... WebJul 3, 2024 · A port connected to terminals does not participate in spanning tree calculation. Otherwise, the convergence of the STP network topology will be lowered. In addition, status changes of the port may cause network flapping, interrupting user traffic. WebIn RSTP, only non-edge ports moving to the forwarding state cause a topology change. Consequently, a loss of connectivity is no longer considered a topology change, which is contrary to 802.1D. That is, a port moving to a blocking state no longer generates a TC. When an RSTP bridge detects a topology change, the following happens: rcmp oliver
