Hey there,

New post just went live on ignaonline.com — this one is a deep dive into Spanning Tree Protocol and Rapid STP on Cisco IOS-XE.

If you've ever had a network outage that turned out to be an STP loop or a misconfigured root bridge, this guide is for you. Sarah walks through the full picture: how root bridge election actually works, the four RSTP port roles and what they mean in practice, and the protection features (PortFast, BPDU Guard, Root Guard, Loop Guard) that prevent the most common production disasters.

You'll also get real IOS-XE CLI output showing healthy vs. broken states, a step-by-step troubleshooting workflow for topology change storms, PVST+ load balancing config, and the command reference every network engineer should have memorized.
