Spanning Tree Protocol is one of the most vital tools for preventing switching loops, and this episode delivers a comprehensive walkthrough of how it works. You’ll learn about the original IEEE 802.1D STP protocol, including how root bridge elections work, how port roles are assigned, and what port states (blocking, listening, learning, forwarding) mean. We illustrate the entire STP process using simplified examples that clarify how switches avoid creating loops while still providing redundancy.

Then we shift into Rapid Spanning Tree Protocol (RSTP), which improves upon traditional STP with faster convergence and streamlined port roles. You'll understand how RSTP simplifies the process, adds Edge Ports, and reacts quickly to topology changes. These protocols often show up on the exam and play a vital role in real-world switch design and recovery planning. If you’re managing redundant links or troubleshooting port behavior, this episode gives you everything you need to speak STP fluently.
