Understanding Layer 3 Networking

We discuss layer 3 networks and how layer 3 switches can route traffic between isolated VLANs, allowing them to communicate with each other. Learn about the basics of IP addressing, including IP address classes and subnet masks. Additionally, how to identify the network ID and unique host on a network is key to understanding how hosts within a VLAN can communicate with each other. Finally, the video explains how routers play a role in connecting hosts on different subnets by having interfaces that belong to the network IDs of each of the subnets.
