This learning path is a comprehensive, progression-driven curriculum designed to take network engineers from core Layer 2/3 fundamentals all the way to architect-level mastery of VXLAN EVPN — one of the most critical technologies underpinning modern data center and cloud networking. Spanning multiple structured modules, the path is carefully sequenced to build knowledge layer by layer, ensuring that each concept is grounded in what came before and every advanced topic is supported by a solid technical foundation. The journey begins with a deliberate refresher of networking fundamentals — Ethernet, VLANs, IP routing, and ARP — not as a review for its own sake, but to reframe those concepts through the lens of scalability challenges that VXLAN EVPN was built to solve. From there, learners explore the evolution of data center design, the mechanics of overlay networking, and the inner workings of VXLAN itself, before advancing into the EVPN control plane, distributed routing models, multi-tenancy, and high-availability designs. Throughout the path, the curriculum maintains a strong emphasis on real-world applicability and multi-vendor relevance, with content aligned to production deployments on Cisco NX-OS, Arista EOS, and Juniper Junos platforms. Learners will not only understand how VXLAN EVPN works in theory, but will develop the design intuition to architect, validate, and defend fabric deployments in complex, large-scale environments. Advanced modules extend the curriculum into automation and programmability, multi-site and inter-DC architectures, hybrid cloud integration, and emerging trends such as SRv6 and AI-driven network operations. This learning path is built for engineers at the CCNA level and above who are ready to move beyond traditional campus and enterprise networking into modern data center and cloud infrastructure. It is equally valuable for seasoned professionals seeking to formalize and deepen their VXLAN EVPN knowledge, close vendor-specific gaps, or transition into architecture and design roles. Whether you are preparing for a professional certification, building a lab curriculum, or enabling a team of engineers, this path provides the structure, depth, and practical grounding to make that outcome a reality. Look for part 2 of this series, where we dive into advanced VXLAN techniques such as flood and learn, MP-BGP EVPN, multi-tenancy, and troubleshooting.

This learning path introduces you to deploying and operating data center fabrics using Arista CloudVision Portal as your centralized orchestration and automation platform. You'll onboard Arista switches into CloudVision, reconcile their configuration with configlets, and build a VXLAN EVPN fabric using MLAG, VRFs, and Layer 2/Layer 3 networks for tenant segmentation. You'll then configure inter-VRF route leaking, and conclude by integrating multiple fabrics in a scalable, multi-domain architecture, all while leveraging CloudVision for centralized visibility and streamlined operations.

There are several universal architectures in the Arista design portfolio. The Enterprise Universal Cloud Network can be used in the data center and in the Cognitive Campus, and the Enterprise Anycloud Network expands beyond the data center. All of these designs deliver the Arista Unified AnyCloud Architecture offering unified orchestration, management and telemetry with CloudVision. Arista's guiding principles are Universal(Common architectures from small to huge), Simple(a single operating system for all platforms and hardware), Open(standards-based features and functions), Programable(Easy to use APIs and automation), and Visible(Full state Telemetry and flow information) The key to these guiding design principles is the use of the Arista EOS architecture for its hardware and software-based devices. EOS is based on a Linux kernel, standard and fully open. EOS uses agent processes, that use a Publish/Subscribe model to populate the NetDB on each device which contains all device states. NetDB can then be used by Aristas CloudVision products to offer full-state telemetry and flow information for the entire Universal Architecture. Because Arista is using a single binary for all hardware and software-based devices Arista can implement hardware abstraction. Unlike some other manufacturers, Arista uses the latest Merchant Silicon and when coupled with the standard open EOS kernel allows very fast development cycles, fewer bugs, and faster adoption by customers since it is the same EOS.
