You heard the words Spanning Tree, now it is time to understand what it is all about. We start with the very beginning, discussing how L3 uses a mechanism to prevent loops. We quickly find out that L2 does not have this mechanism and why Spanning Tree is needed. Then we enter the world of Spanning Tree. Exploring how spanning tree forms it topology and the election processes.

From there we enter into a step by step process, understanding how Spanning Tree starts to build its own topology. We learn about the Root Bridge, Root Ports, Designated Ports, Blocking ports, and so on.

If you want to really understand Spanning Tree, this is where you begin. I assure you that after you watch this 2.5hr lecture and take the 5 quizes, you will have a solid Spanning Tree Basics foundation.

This was a class that I ran and recorded. I took that footage and edited just for Udemy students. Please let me know how you like this course, for there is more to come.

CCIE #54443

My name is Kiel Martin CCIE #54443. I have been teaching Cisco topics for a while now and I take great pride in getting others to use the equipment to get the answers that they are seeking. So I spend lots of time helping others to learn the basics and advanced topics of Routing and Switching. We spend lots of time behind the command line and using labs to provide us the answers that theory claims to exist. Come learn the concepts the right way.

When is comes to understanding what it takes to pass, I do not sugar coat it. I currently work as a Network Engineer in a Multi-Tier Large Enterprise environments. My teaching techniques are based on the concept of keeping it simple and straight to the point. You will notice a difference in my teaching immediately.
