RSTP = 802.1wNote The main points: Fast convergence is based on switch-related process synchronization To open a command:-Spanning Tree mode MST-Spanning Tree mode Rapid-pvst The synchronization process only occurs on the peer Non-edge port (the full Duplex,non-edge to have the Bpdu,edge port configured portfast command) Note: If Portfast is not configured on the edge port and the port is full duplex, the host does not reply to agree when it receives the rapid

The STP (Spanning tree Protocol) is the acronym for the Spanning Tree protocol. This protocol can be used to establish a tree topology in the network, eliminate the loop in the network, and can realize path redundancy through certain methods, but it is not certain that path redundancy can be realized. Spanning tree protocol is suitable for all manufacturers of network equipment, in the configuration and reflect the functional strength of the differenc

Spanning Tree [01] Introduction to Spanning Tree and explanation of STP principlesWhy do we need to use the Spanning Tree Protocol? The Spanning Tree Protocol is a layer-2 link protocol. As shown in, vswitches play an important role in L2 Networks. If a switch fails, the use of the network may be affected. To avoid spof, in the actual L2 link, link redundancy is used, that is, multiple contact connections are used between switching devices, that is, m

The Spanning Tree Protocol (STP) is an important concept and Technology in switched Ethernet. The purpose of this Protocol is to achieve redundant connections between switches while avoiding the emergence of network loops, achieve high network reliability. It transmits the Bridge Protocol Data Unit (BPDU) between switches to inform each other of information such as the bridge ID, link nature, and root bridge ID of the switch, to determine the root bri

STP (Spanning Tree Protocol) is a layer-2 management protocol that selectively blocks redundant network links to eliminate L2 network loops, it also supports link backup. Like other protocols, the Spanning Tree Protocol is constantly updated with the continuous development of the network. The Spanning Tree Protocol is a broad concept. It does not refer to the STP protocol defined in IEEE 802.1d, but includ

(second step) and the specified port (the third step) has established a loop-free topology map. You can think of this topology diagram as a wheel, the root bridge is the axis, the active non-ring path (vehicle spokes) outward radiation. On a network with stable network conditions, only the root bridge sends BPDUs outward on the network. When the above three steps are completed, the network converges on the loop-free topology, and the other topology changes are handled by the topology Change p
