A BPDU is encapsulated in an Ethernet frame. Its destination MAC address is a multicast MAC address, 01-80-C2-00-00-00. STP BPDUs are classified into the following types: Configuration BPDU: used to calculate an

(for example, detects the handshake signal and the like), in terms of software implementation, the timer, namely, the max age timer which controls the expiry of the BPDU is actively expired, and the topology change message is transmitted to the whole topology structure. Wherein, the way for...
