WebOct 8, 2024 · ALL switch networks have loops. If they have no loops then they have no redundancy, and we like redundancy. It's important to learn to differentiate between loops at Layer 1 and loops at Layer 2. Loops at Layer 1 are required. They are controlled/manipulated at Layer 2 by spanning-tree and the network engineer knowing his or her stuff.

WebThe Spanning Tree Protocol (STP) is a network protocol that is used to eliminate bridge loops in Ethernet LANs. STP prevents network loops and associated network outage by blocking redundant links or paths. The redundant paths can be used to keep the network operational if the primary link fails. WebThe gold standard for preventing switching loops is the Spanning Tree Protocol (STP). It works by creating a group of switches that exchange information via special frames called bridge protocol data units (BPDUs) to create and maintain a loop-free topology.
