Description

EIGRP is a routing protocol that is commonly used on enterprise networks, but often it is not completely understood. In this course, Protocol Deep Dive: EIGRP, you will learn foundational knowledge of EIGRP. First, you will learn about the EIGRP's essential concepts, which will then be built on as the course continues. Next, you will focus on EIGRP neighborships, how they work, and what can prevent them from working. You will also learn how information is exchanged between EIGRP devices and how to understand why each message is sent, as well as move to a lab environment where you can see the concepts in operation. Finally, you will explore a few more advanced EIGRP topics that are commonly seen on modern networks, and then end the course with a module on EIGRP load balancing and how its operations differ from other routing protocol options. When you are finished with this course, you will have the skills and knowledge of EIGRP needed to successfully navigate its use in most common enterprise environments.

Course Overview
Hi everyone. My name is Sean Wilkins, and welcome to my course, Protocol Deep Dive: EIGRP. I am a network engineer, author, and technical editor at InfoDispersion. EIGRP is a routing protocol that is commonly used on enterprise networks, but often is not completely understood. This course focuses on providing the learner with a more in-depth understanding of EIGRP and its operations. While this course doesn't require previous EIGRP knowledge, it will help in ensuring the student have a perspective of where it fits inside networking generally. Some of the major topics that we will cover include core EIGRP concepts, EIGRP neighborships and their establishment, EIGRP packet and message types and their uses, EIGRP route summarization, and EIGRP load balancing. By the end of this course, you'll have an in-depth knowledge of EIGRP and its operations and be able to better navigate its use in modern enterprise environments. I hope you'll join me on this journey to learn about EIGRP with the Protocol Deep Dive: EIGRP course at Pluralsight.

Digging into EIGRP Relationships
Hello everyone, and welcome to Protocol Deep Dive: EIGRP. My name is Sean Wilkins, and this is the Digging into EIGRP Relationships module. This module begins a discussion on EIGRP relationships. In this module, we will start with a section on the forming of a neighborship, specifically discussing the requirements to form a neighborship and the types of packet used before moving into the lab and showing neighborships forming and what it looks like. Next, we will have a section on EIGRP timers covering what the timers are and how they are used before moving back into the lab to see them in action. And finally, our last section will be a primer on the EIGRP packet, including a review of the different fields that are used. So now with all this out of the way, let's get started.

Determining How Information Is Exchanged with EIGRP
Hello everyone, and welcome to Protocol Deep Dive: EIGRP. My name is Sean Wilkins, and this is a Determining How Information Is Exchanged with EIGRP module. This module goes deeper into EIGRP communications, specifically covering the different ways that EIGRP devices communicate and the messages that are used. In this module, we begin with a section discussing the different EIGRP route states, as well as EIGRP's use of split horizon and poison reverse. In the next section, we will detail the different EIGRP message and packet types that are used, including a review of how they are used in combination with each other to inform the EIGRP process. In the next section, we will talk about the different common types of EIGRP TLV, their structure, and the different situations that they are used in. So now with all this out of the way, let's get started.

Showing How Information Is Exchanged with EIGRP
Hello everyone, and welcome to Protocol Deep Dive: EIGRP. My name is Sean Wilkins, and this is the Showing How Information Is Exchanged with EIGRP module. This module takes the theory that was covered in the previous module and moves it into a practical lab environment. We begin with a demonstration of neighborship establishment, focusing on the different packets that are initially exchanged. We then move into a demonstration of how EIGRP devices communicate when there is a change in the network, including the adding and removing of different routes, as well as device restart and reset. Next, we move into a demonstration of external routes, focusing on how these routes are propagated between EIGRP devices. And we finish up with a demonstration of authentication and how this changes the packets that are exchanged. So now with all this out of the way, let's get started.

Covering EIGRP Advanced Topics
Hello everyone, and welcome to Protocol Deep Dive, EIGRP. My name is Sean Wilkins, and this is the Covering EIGRP Advanced Topics module. This module will move into a couple of topics that tend to be considered a bit more advanced, and because of this require some amount of base EIGRP knowledge to understand. We will begin with a section on EIGRP summary routing, specifically discussing how and why it might be used, along with an example in the lab. Next, we move into a section that discusses how the summary and stub features can be used to limit query behavior, as well as spoke router transit. And in the final section we move into discussing the significance of the EIGRP router id, and how it's misconfiguration can cause problems within a network. So now with all this out of the way, let's get started.

Reviewing EIGRP Load-balancing
Hello everyone, and welcome to Protocol Deep Dive: EIGRP. My name is Sean Wilkins, and this is the Reviewing EIGRP Load-balancing module. This module will include a discussion of load balancing specifically covering how EIGRP's implementation differs from other routing protocol options. In this first section we will discuss load balancing theory, specifically covering how EIGRP implements load balancing and an example of its implementation. The second section will then move into the lab and show how EIGRP load balancing is configured and how it can be shown with common Cisco iOS show commands. So now with all this out of the way let's get started.
