VxLAN Explained: Header Format & Encapsulation Deep Dive 🔍

#VxLAN technical deep dive! VxLAN creates virtual layer-2 networks in an overlay network. They are called VNI’s. During encapsulation, the VTEP adds extra headers, using a specific frame format. This is to pass this traffic over the underlay network in a tunnel, using routing.<br /><br />In this training video, we’re going beyond the basic concepts, in a deep dive look at the #encapsulation process, and the headers that VxLAN use. The VxLAN vs #VLAN differences are further explained here.<br /><br />We’ll consider some more VxLAN terminology, and provide a primer to the VxLAN packet flow.<br /><br /><br />Read more at:<br />https://networkdirection.net/VxLAN+Frames<br /><br /><br />I also suggest reading ‘Building Data Centers with VXLAN BGP EVPN’ by Lukas Krattiger<br />https://click.linksynergy.com/link?id=RL4E*8CmbSY&offerid=145238.2463561&type=2&murl=http%3A%2F%2Fwww.ciscopress.com%2Ftitle%2F9781587144677<br /><br /><br /><br />Part 1: Fundamentals - An introduction or primer into the basic concepts and terminology.
