Current Trends in DC Networking - Arista VXLAN


In my last post I covered the fundamentals and basic design of VxLAN. Now its time to get to the fun stuff, configuration! This post will focus on Arista's VxLAN configuration using vEOS.  Arista has been making serious traction in the DC space.

Throughout this series we will be building on the following topology. EBGP will be used as the routing protocol between spine and leaf nodes as it is the popular option in the DC at the moment. Each leaf will peer with both spines, but notice there is no connection between spines. Why? Well as usual Ivan Pepelnjak does a great job explaining it here.

Leaf switches will act as both the VLAN gateway and VTEP. Two vlans/VNIs will be extended between the three pods.



So lets get started!
