Course Description

This IS-IS MASTERCLASS will encompass just about everything you wanted to know about this extremely important protocol.

It will give you a deep understanding of how important IS-IS is and how you can implement it in your infrastructure.

This course will be filled with the details of IS-IS and how it is usually misunderstood, although it is one of the most important routing protocols that should be implemented in today's IT environment.

You will be able to follow my labs by pausing the videos and replicating what I have done.

I am a strong believer in hands-on and I believe, that in almost two decades of teaching, this is the best method for students to learn and retain the information acquired.

I have always believed that practicing is the best method of learning and therefore, practicing by doing the work and replicating what you see in my labs seems to have worked for most of my students and I believe it will also work for you.

All you have to do is follow my work and replicate it and you should be on your way to learning IS-IS!

I hope you get the information you need out of this course to apply IS-IS in a lab environment and in the real world.

Happy studies!

NOW...what you wanted to know about me but were afraid to ask:

If you are tired of the same old methods of learning and want someone that is pretty much unconventional, but at the same time will provide you with an enjoyable learning experience in layman's terms...then please preview my courses and you will discover that I am your guy.

I am a Network Engineer with many years in the field and in the teaching industry.

So, if anyone can get you certified it's me.

My teaching experience stems from teaching at institutions like Palm Beach Community College, New Horizons, Florida Career College (now Anthem College) and The Academy of South Florida not to mention that I also do private consulting.

Here I bring the classroom to you.

I am in several eLearning Platforms worldwide, to include my own...but you can look it up since I'm not allowed to put it here.

Courtesy of the internet, I have been teaching students from all over the world and all walks of life.... thank goodness for technology ;-)
