This is an intro overview of VxLAN, a network overlay technology commonly used in the cloud. It is vendor independent so it can run on #Cisco #Nexus, NSX, Open vSwitch, and many more. It can even be used in virtual appliances like the CSR1000v. #VxLAN is a sophisticated way to manage layer-2 networks. It’s like VLAN, with some very special enhancements. It has a different perspective on the network. There is the underlay fabric, which uses routing such as eigrp or ospf, and the overlay, where the virtual networks live. LAN segments are called VNI’s. VNI’s keep traffic separate, Just like VLANs. This is part of how VxLAN is used for multitenancy. Traffic within a VNI reaches a switch with a special interface called a VTEP. The traffic is encapsulated and forwarded over the routed network through a tunnel. This training series is VxLAN fundamentals explained. Think of it as VxLAN for dummies!
