EVPN (Ethernet Virtual Private Network) is a modern networking technology that helps organizations connect their different office locations and data centers more efficiently. Think of it like creating secure, private highways between different company locations that can carry large amounts of data traffic. Network engineers use EVPN because it makes networks more flexible, easier to manage, and more reliable than older connection methods. It's similar to other technologies like VPLS or VXLAN, but EVPN is considered more advanced and easier to work with. When you see EVPN in job descriptions, it usually means the role involves designing or managing large-scale network connections for businesses.
