In networking, one of the critical challenges faced by administrators is preventing loops in Layer 2 Ethernet networks. Loops occur when multiple active paths exist between switches, causing frames to circulate endlessly. This can lead to broadcast storms, MAC table instability, and network outages. The Spanning Tree Protocol (STP) is a solution designed to maintain a loop-free network topology while allowing redundant links for fault tolerance. STP operates by logically blocking redundant paths, thereby ensuring there is only one active path between any two network devices. This protocol dynamically adapts…
