Appendix - The Lab

Advanced fabric configuration for Arista Data Center

Our data center topology has one spine switch and two leaf switches. An EVPN/VXLAN fabric consists of an underlay network that dynamically provides the routing for the VXLAN (VTEPS) to establish and an overlay network that provides the routing information for the host devices to be able to communicate. Simply put, VXLAN allows layer 2 tunnels over a layer 3 network. In this small data center fabric example, you will use BGP as our routing protocol for both the underlay and overlay.

Note

For more information on VXLAN configurations on Arista, see https://www.arista.com/en/um-eos/eos-vxlan-configuration.

Generating the underlay configuration

The underlay in our topology is using eBGP (i.e., different autonomous systems). The following table outlines the BGP Autonomous System Number (ASN) for each of the devices in our fabric.
