## AI overview

This article explains how to choose among BGP, EVPN, VXLAN, MPLS VPN, SR-MPLS, and SRv6 based on network requirements. It distinguishes ordinary hop-by-hop IP forwarding from traffic engineering and from multiple forwarding domains such as L2VPNs and L3VPNs.

## Source excerpt

Daniel Dib asked an interesting question on LinkedIn when considering an RT5-only EVPN design: I'm curious what EVPN provides if all you need is L3. For example, you could run pure L3 BGP fabric if you don't need VRFs or a limited amount of them. If many VRFs are needed, there is MPLS/VPN, SR-MPLS, and SRv6. I received a similar question numerous times in my previous life as a consultant. It's usually caused by vendor marketing polluting PowerPoint slide decks with acronyms without explaining the fundamentals1. Let's fix that. Read more ...
