## AI overview

A hands-on guide to building a layer-3-only EVPN lab with netlab. The lab uses Arista cEOS containers, two switches, two VRFs, four Linux hosts, OSPF, BGP, VXLAN, and EVPN, with instructions for using other supported devices.

## Source excerpt

A few weeks ago, Roman Dodin mentioned layer-3-only EVPNs: a layer-3 VPN design with no stretched VLANs in which EVPN is used to transport VRF IP prefixes. The reality is a bit muddier (in the VXLAN world) as we still need transit VLANs and router MAC addresses; the best way to explore what's going on behind the scenes is to build a simple lab.
