What Happens When a Switch Loop Crashes a Network?

In this episode of LAN Lab Guides, we explore Spanning Tree Protocol (STP) and why it's one of the most important technologies in modern networks.

What happens when a network has multiple paths between switches? Without STP, a single redundant cable can create a switching loop, causing broadcast storms, MAC address table instability, and network outages. In this video, I demonstrate how these loops occur and how STP prevents them.

Using both Cisco Packet Tracer and Cisco Modeling Labs (CML), we'll walk through:

How switching loops are created
Why broadcast storms occur
Root Bridge election
Root Ports, Designated Ports, and Alternate Ports
How STP blocks redundant links
Network redundancy and failover

Whether you're studying for the CCNA, learning networking fundamentals, or working through a LAN Lab course, understanding STP is essential for designing reliable Layer 2 networks.
