Rstp root bridge election
WebThe STP process works by default on Cisco switches and begins with the root switch election. The election is based on the bridge IDs (BIDs) sent in the BPDUs. Each switch that participates in STP will have a 8-byte switch ID that comprises of the following fields: 2-byte priority field – by default, all switches have the priority of 32768. WebJan 18, 2024 · BPDU. Spanning tree path cost value can be defined as the sum of the port costs of all the ports included in the path from non-root switch to root switch. It is inversely proportional to the bandwidth of the path and hence path with the lowest path cost value is considered more efficient than one with a high path value.
