The Cisco ACI: Tenant & Fabric Connectivity learning path is the second part of our ACI fundamentals training, following the "Cisco ACI Fabric Initialization and Hypervisor Connectivity" path. This path covers two key areas: 1) Fabric Infrastructure configurations, which involve physical fabric setup, including vPCs, VLANs, loop prevention, underlay BGP protocol, etc. 2) Tenant Configurations, defining logical constructs like application profiles, bridge domains, and EPGs. In this Learning Path, students will learn to create Tenants, Application Profiles, Bridge domains, and EPGs, by using objects for connectivity within a physical ACI fabric. They will also discover how to connect Layers 2 and 3 to external networks and explore methods for segmentation using contracts and filters to support both Inter-EPG and Intra-EPG segmentation.

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.
