### AI overview

This article outlines an Internet-based data center interconnect built with VyOS, using BGP EVPN as the control plane and VXLAN as the data plane. It compares centralized and distributed routing, discusses Layer 2 and Layer 3 interconnect choices, and covers resiliency considerations such as redundancy, convergence, gateway placement, and failure domains.

### Source excerpt

Modern data centers increasingly rely on IP fabrics that use BGP EVPN as the control plane and VXLAN as the data plane. This standards-based architecture extends Layer 2 and Layer 3 services across an IP underlay while keeping a clear separation between the physical network and tenant or service networks. This post summarizes the routing models, interconnect options, and resiliency considerations behind an Internet-based Data Center Interconnect (DCI) built on VyOS. For the complete configuration and validation steps, see the EVPN-VXLAN DCI Deployment Guide.
