In this video we're going to take a look at OSPF.
Open Shortest Path First (OSPF) is a widely used and supported routing protocol.
It's an interior gateway protocol (IGP) meaning it been designed to be used within a single autonomous system. It also falls under the category of Link-state routing protocols.
Routers running OSPF learn about the enter network in order to create routes. They do this by flooding Link State Updates. There are three steps to the process.
Become neighbours - Two routers running OSPF on the same link agree to form a neighbour relationship
Exchange database information - The neighbouring routers swap their LSDB information with each other
Choose the best routes - Each router chooses the best routes to add to its routing table based on the learned LSDB information

The official Cisco coursework for this topic is so wordy and obtuse I really must thank you for posting this video. You explained in 13 minutes what Cisco failed to explain in 15 minutes and several pages of dense acronym-laden text. You are the real MVP

Using some cisco white papers to lab this up in EVE-NG and referring back to this video gave me my "Aha" moment... Great stuff on the channel keep it up.

Newbie question: is link speed the best way to determine cost? What if a particular link is already carrying heavy traffic? In that case another route might be slower in an absolute sense, but if not congested would be the best route at that particular time. Maybe something like dynamic cost is required, based on the flow of traffic through the link.
