This eBook is written by me (author), I am working as network engineer since last 5 years, I have good command over routing & Switch concept. I am working in this technology and served many clients based on their daily networking issue in their environment.

For more information about me. Kindly write to dharmendra857295@gmail.com. I will happy to help you.

This eBook is a guide and serves as a first guide. In addition, please get expert advice or you can write to dharmendra857295@gmail.com for any query, we will be happy to help you. This boook has been written in advise of many my experts colleagues who have also good command over netwoking. They are listed at the end of this book.

Introduction of Spanning Tree Protocol

What is spanning tree protocol in Switching environment? Spanning tree protocol is a link management protocol which provides path redundancy while preventing undesirable loops in the network because loops are deadly to network. In STP environment, switches exchanges bridge protocol data unit between each other. By exchanging BPDU (bridge protocol data unit) switch itself select a root bridge based on low priority or low mac address of switch. By default, all switches have same priority value which is 32768. So, in this case MAC address of switches is tie breaker. Lower mac address wins her and select as root bridge.

 

This was the basic understanding of spanning tree protocol. We are going to cover each topic related to spanning tree in detail with practical. Please read this book carefully. It is not going to so long, will be short book which would be interesting, this will help network engineer to cover their all concepts of spanning tree protocol.

 

Why Spanning Tree Required?

Look at below topology, we have 2 switches which are also connected with 2 PCs. In this scenario, if link between Switch0 to Switch1 got failed. The communication between both PCs will be dropped because this is the single point of failure.

We can add 1 more link between both switches to avoid this single point of failure as in the picture below.

Now here is one problem, link redundancy
