Cisco ACI Fundamentals Lab Part 1
This lab is the Cisco ACI Fundamentals Lab Part 1, and after completion, the student can launch Cisco ACI Fundamentals Lab Part 2 to complete the entire lab. The lab uses the ACI virtual simulator based on ACI Version 6, emulating an APIC, 2 leafs, and a spine. Part 2 uses a shared physical ACI fabric to complete the policy and verify data plane connectivity.
The ACI Virtual Simulator was needed to demo the building of the ACI fabric from scratch, bootstrapping the APIC, adding the spine and leafs, fabric discovery, and completing VMM integration. Since the Cisco ACI Fundamentals Lab, Part 2 is a shared on-demand environment, to decouple the APIC build process from the APIC policy creation. Due to limitations, the virtual ACI fabric is a control plane-only simulator, and no data plane testing (Ping, SSH) can get done for validation. Cisco ACI Fundamentals Lab Part 2 uses a Tenant inside of a physical ACI, and data plane functionality can get tested ( Ping, SSH)

AI's Invisible Bottleneck: Why AI Stalls at the Network, not the GPU
For many, AI success isn't limited by how many GPUs you can buy; it's limited by how fast those GPUs can talk to each other without tripping over the plumbing. In this episode of the AI Proving Ground Podcast, two of WWT's top networking minds —Justin van Schaik and Eric Fairfield — lay out the real choke points slowing AI projects to a crawl and how powerful, modernized network architectures are quietly rewriting the rulebook for scaling AI.
6 Steps to Understanding Cisco ACI
When understood, these six concepts will help anyone new to ACI to understand a more detailed technical discussion.
Arista EVPN VXLAN 101 Lab
This Arista MP-BGP EVPN Lab provides exposure to the new technology and capabilities of the products used. This lab introduces the Arista Cloud Vision Portal(CVP) and introduces students to the basics of building the VXLAN L3LS Underlay, MP-BGP overlay, MLAG, Asymmetric and Symmetric IRB, and eternal L2/L3 connectivity. It also provides an in-depth look at Arista Cloud Vision Portal(CVP) and how to use it for day 0,1 building and day 2 operations. 3 VXLAN EVPN scenarios based on best practices from the Arista design guides, ACE3 course material, Arista TAC support the Arista EOS forum posts. There are many different ways to create an Arista-based VXLAN EVPN fabric; these labs present a migration phase from a standard 3 tier VLAN and SVI-based network to a VXLAN fabric, Then the fabric changes to using Asymmetrical IRB and Symmetrical IRB. BGP routing is the underlay, overlay and connectivity to the remote data center under migration.

Open Shortest Path First (OSPF) Intermediate
This intermediate learning path on Open Shortest Path First (OSPF) is tailored for network professionals who are ready to move beyond the basics and develop a deeper, more practical understanding of OSPF in enterprise networks. The path explores key deployment and optimization techniques including route redistribution between OSPF and other protocols, effective route summarization at ABRs and ASBRs, and implementing route filtering to control routing information flow. It also covers OSPF area types in detail, including standard stub areas, totally stubby areas, and Not-So-Stubby Areas (NSSA), with guidance on when and how to use each to simplify routing and improve scalability. Throughout, the learning path emphasizes best practices, common design mistakes to avoid, and hands-on configuration strategies to help learners confidently apply OSPF in complex, real-world environments.
