Les boucles réseau, pourquoi un simple câble peut faire tomber tout un réseau ? #8

Watch HERE:    • Les boucles réseau, pourquoi un simple câb...   In this video, we explain a critical problem in Ethernet networks: Layer 2 loops and broadcast storms. Without a protection mechanism, a few switches connected in a loop can quickly saturate the network's bandwidth and CPU. That's precisely why the Spanning Tree Protocol (STP) exists. In this video, you will understand: Why Layer 2 loops are dangerous How a broadcast storm can bring down a LAN How Spanning Tree detects and blocks loops How switches elect a Root Bridge The difference between Root Port, Designated Port, and Blocking Port The differences between STP, RSTP, and MSTP Best practices for choosing the right Root Bridge 0:00 Introduction 2:12 Normal Operation 4:06 Loops 7:20 Spanning Tree 10:20 Conclusion
