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 on foundational Open Shortest Path First (OSPF) provides a comprehensive introduction and deep dive into the core aspects of OSPF. It starts by explaining the basics of OSPF, including its purpose, operation, and fundamental concepts such as OSPF Neighbors, advertising routes, authentication, OSPF network types, and many others. This learning path aims to equip network professionals with the knowledge needed to manage and optimize OSPF in real-world environments, emphasizing best practices and common pitfalls.

In this Learning Path, you'll build a foundational understanding of enterprise networking and the Extreme Networks platform, starting with core switching and routing principles. From there, you'll learn how IS-IS serves as the control plane behind Extreme Fabric Connect, building and sharing topology information across the fabric so VLANs can reach each other automatically, without manual route configuration. You'll then see how BGP connects the fabric to the WAN, enabling routing between sites and internet access through Extreme SD-WAN appliances, whether traffic is routed centrally over the WAN or broken out locally based on policy. Together, these technologies show how modern enterprise networks are designed, connected, and extended across multiple sites with Extreme Networks.
