Introduction2:53
This lecture is the introduction that will let you know the topics we will be covering in this IS-IS course

History of IS-IS15:13
In this lecture, we will cover how IS-IS came to be and its history
Comparing IS-IS to OSPF18:00
In this lecture, we will be comparing OSPF vs IS-IS and the advantages of using IS-IS
IS-IS vs. OSPF Terminology11:12
In this lecture, students will learn the new terminology used by IS-IS as a link-state routing protocol
OSPF Single Area Configuration13:57
In this lab, we will be configuring a single area OSPF and analyzing what it is advertising.
Here, students must replicate the GNS3 lab.
IS-IS Single Area Level 1 and Level 2 Config19:38
In this lab, we will be configuring a single area IS-IS and analyze the level type of routers.
Here, students must replicate the GNS3 lab.

How to choose an IGP17:45
In this lecture, students will learn the differences between ALL the IGP routing protocols in order to make a logical choice.
Other Reasons to consider IS-IS5:15
In this lecture, students will learn other reasons why IS-IS is a good routing protocol choice for Large Enterprise Networks.
IS-IS Levels8:09
In this lecture, students will learn the different level types of routers that can be used in IS-IS

Multi-Area OSPF9:48
In this lab, students will configure multi-area OSPF while analyzing what is being advertised and the rigid restrictions of connecting to area zero.
Students need to replicate the GNS3 lab as shown in the lecture
Multi-Area IS-IS16:42
In this lab, students will configure multi-area IS-IS while analyzing the level type of router and the flexibility of not having to connect to an area zero
Students need to replicate the GNS3 lab as shown in the lecture

Requirements

Students should have a Network+ understanding of Networking.
Students should have a simulator or emulator (i.e.: GNS3, Eve-NG, or CML2) to practice with

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!

Who this course is for:

Network Engineers, Network Technician or anyone dealing with Networks
