This is Part2 of 'inter-Vlan VS VXLAN Routing'. In this video, I have demonstrated how VXLAN routing works. Configuration and in-depth analysis of Asymmetric vs Symmetric Routing in VXLAN.
This video is for VXLAN beginners. We will configure a simple topology step-by-step from scratch and see an in-depth packet walk from the very first packet. I will be using Arista switches; however, the concept is standard, so it works similarly for other vendors like Cisco, etc.
