Hello everyone,

I just released Part 1 of my two-part lesson on Routers:

https://www.youtube.com/watch?v=AzXys5kxpAM

This video discusses Routers and everything Routers do to facilitate communication between networks.

We first describe that Routers and Hosts are very similar, then provide a formal definition of a Router and Host (and Nodes). Then we discuss the Routing Table and show you how a Router uses it to route packets. Finally, we illustrate the three methods a Router populates its Routing Table: Directly Connected routes, Static Routes, Dynamic Routes.

The specific time stamps to each of these sections are below:

• 00:00 - Start
• 00:20 - Pre-requisites (Networks, Routing, OSI Model, L2 & L3, Everything Hosts do, ARP)
• 02:09 - Routers need an IP Address and MAC address (just like hosts)
• 03:19 - Formal Definitions: Routers and Hosts (and Nodes)
• 05:02 - Routers need an IP/MAC for EACH Network
• 05:45 - Routing Table
• 07:22 - Directly Connected Routes
• 09:27 - Using the Routing Table to route Packets
• 10:39 - Static Routes
• 11:50 - Forward and Return path
• 13:04 - Dynamic Routes
• 14:35 - Dynamic Routing Protocols
• 15:31 - Summary & Key Points
• 16:24 - Network Fundamentals - Full Course - Details

A lot of effort was put into this video, and I feel confident in saying you will be hard pressed to find these ideas communicated in a more lucid way.

Either way, feedback is always appreciated (positive or negative). So please let me know what you think.
