Designing Cisco Enterprise Networks: Routing Protocols

by Sean Wilkins

This course will teach a number of the most commonly implemented Enterprise routing protocols including EIGRP, OSPF, IS-IS, and BGP and how they relate to Cisco network design recommendations.

What you'll learn

Many engineers work their whole careers without ever really looking under the hood to understand why a network was designed the way it was. Some of this is because their day-to-day duties don't require this knowledge, and some of this is because an engineer chooses to focus their knowledge on becoming exceptional operational engineers. In this course, Designing Cisco Enterprise Networks: Routing Protocols, you will take a closer look at the routing protocols that are commonly implemented in Enterprise networks, specifically covering EIGRP, OSPF, IS-IS and BGP. First, you will review the basics of each of these protocols and some amount of the inner-workings of each of the protocols. Then, you will explore the basics of routing protocols including the different types and behaviors that are common between them. Next, you will learn about EIGRP, basic EIGRP concepts including neighborships, metrics, the topology table, summarization, and stub. After that, you will see basic OSPF concepts including neighborships, metrics, areas, the Link state database, summarization, and stub. Finally, you will explore IS-IS concepts including neighborships, metrics, and areas. You'll wrap up with a review of the basic BGP concepts including neighborships or peerings, and path selection. When you are finished with this course, you will have a firm base of understanding of the different routing protocols that are commonly implemented in an enterprise environment.
