Why should I take this module?

Welcome to Single-Area OSPFv2 Concepts!

Welcome to the first module in CCNA Enterprise Networking, Security, and Automation v7.0 (ENSA)!

Imagine that it is time for your family to visit your grandparents. You pack your bags and load them into the car. But this takes a bit longer than you planned for and now you are running late. You pull out your map. There are three different routes. One route is no good because there is a lot of construction on the main road and it is temporarily closed. Another route is very scenic, but it takes an additional hour to get to your destination. The third route is not as pretty but it includes a highway, which is much faster. In fact, it is so much faster that you might actually be on time if you take it.

In networking, packets do not need to take the scenic route. The fastest available route is always the best. Open Shortest Path First (OSPF) is designed to find the fastest available path for a packet from source to destination. This module covers the basic concepts of single-area OSPFv2. Let’s get started!
