Router Hierarchies and Route Summarization - Networking Fundamentals - Lesson 5 - Part 3

In this video we provide a brief introduction to Network Design concepts. We discuss how Routers are typically deployed in a Hierarchy, and the benefits this achieves. One of those benefits is the ability to Summarize Routes for the sake of reducing the number of entries in the Routing Table. We show you some examples of Route Summarization, all the way through to the ultimate route summary known as the Default Route (0.0.0.0 /0).

This is Part 3 of our lesson on Routers. It is recommended to have watched Part 1 and Part 2 before watching this video.
