WebJan 27, 2024 · With RSTP, things are somewhat different. In Scenario 1 (Hypothesis 1), both switches will send a Proposal to each other; this is because every RSTP port in Designated Discarding or Designated Learning role/state combination sends out Proposals. However, S3 will ignore S4's Proposal because the BPDU will be inferior to S3's own BPDUs. WebRSTP was developed based on STP and makes supplements and modifications to STP. Disadvantages of STP STP ensures a loop-free network but is slow to converge, leading to service quality deterioration. If the network topology changes frequently, connections on the STP network are frequently torn down, causing frequent service interruption.

WebJan 27, 2012 · The Root Bridge (switch) is a special bridge, which is at the top of the Spanning Tree. The other non-root switches are then branched out from the root switch, connecting to other switches in the Local Area Network (LAN). All bridges (switches) are assigned a numerical value called bridge priority. The Spanning Tree Protocol (STP) is a network protocol that builds a loop-free logical topology for Ethernet networks. The basic function of STP is to prevent bridge loops and the broadcast radiation that results from them. Spanning tree also allows a network design to include backup links providing fault tolerance if an active link fails. As the name suggests, STP creates a spanning tree that characterizes the relationship of nodes …
