Cisco (Viptela) SD-WAN
This Learning Path is designed to Discover and Experience Cisco (Viptela) SD-WAN. The lab environment that supports this Learning Path is virtual and dedicated to each individual consumer.
Border Gateway Protocol (BGP) Foundations
This learning path on foundational Border Gateway Protocol (BGP) provides a comprehensive introduction and deep dive into the core aspects of BGP, the backbone of the internet's routing architecture. It starts by explaining the basics of BGP, including its purpose, operation, and fundamental concepts such as Autonomous Systems (AS), BGP sessions, and the BGP routing table. The series progresses to cover more advanced topics, such as BGP path selection, route advertisement, and the implementation of various BGP attributes like Local Preference, AS Path, and MED. Through practical examples, configurations, and troubleshooting scenarios, viewers gain a thorough understanding of how BGP facilitates global data exchange and the techniques network engineers use to optimize and secure BGP networks. The series aims to equip network professionals with the knowledge needed to manage and optimize BGP in real-world environments, emphasizing best practices and common pitfalls.

Fortinet Security POC: SD-WAN & SD-Branch
In late 2023, a Fortinet SD-WAN/SD-Branch proof of concept (POC) test was completed in the WWT Advanced Technology Center. Here, we present part one of two of the testing results.
Investing in Innovation: Data Centers, AI and Energy
The AI revolution demands power, space, and cooling that most data centers weren't designed to handle. Watch WWT CTO Mike Taylor as he leads an executive fireside chat with Jeffrey Holzschuh (Chairman of Morgan Stanley's Institutional Securities Group), Joe Dominguez (President and CEO of Constellation Energy) and Aidan Kehoe (Managing Partner at Nadia Partners) that touches on the critical decisions and investments needed in energy to power innovations with data and AI.
Understanding Core Routing Technologies
Join Josh Hogan for a concise, introductory webinar on the foundational routing technologies that underpin modern network management. In this session, he will cover key topics such as underlay routing, interior protocols like IS-IS and OSPF, and the critical role of MPLS and transport mechanisms in establishing a resilient network infrastructure. Josh will also discuss how BGP facilitates service sharing, the impact of segment routing on performance, and the growing importance of software control, automation, and intent-based policies in network optimization.

Cisco Catalyst SD-WAN (Viptela) Sandbox (20.9.x)
The Cisco Catalyst SD-WAN 20.9.x Sandbox is a capability of the ATC designed to provide an environment to gain hands-on experience with the latest features in the Cisco SD-WAN solution. Within this lab version, every Edge participating in the SD-WAN fabric is a Catalyst 8000V. The environment that supports the Cisco Catalyst SD-WAN 20.9.x Sandbox is completely virtual, removing any hardware dependencies associated with physical infrastructure.
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.
The Battle of AI Networking: Ethernet vs InfiniBand
This article is not an exploration of who does Ethernet better so much as a direct examination of technology itself. Numbers will be reported as an aggregate means between major players in the AI Networking market and contrasted with equivalent InfiniBand performance. The goal is to answer, at an atomic level, one question: eliminating all other variables, is Ethernet good enough?
Cisco ACI
Cisco ACI is a policy-driven CLOS or Spine/Leaf based switching fabric utilizing layer 3 ECMP routing in the underlay and VXLAN encapsulation in the overlay to transport layer two and layer three traffic East/West across the fabric and North/South in and out of the fabric. ACI consists of the Application Policy Infrastructure Controller (APIC), a centralized controller that manages all aspects of the ACI fabric. The leaf switches are ToR switches that provide connectivity between servers and external networks, and the spine switches are Layer 3 switches that provide ECMP high-bandwidth connectivity between leaf switches. An ACI fabric can be expanded East/West by adding leafs, cabling to the spines, and registering them. ACI was designed to operate as "One Big Switch" (like a chassis-based NEXUS 7K) with the controllers acting like the Supervisors, the spines as fabric modules, and leafs acting as blades. We can decouple these elements from the chassis and place them anywhere in the data center by taking this approach. The leafs (blades) can be placed anywhere in the data center, so you are not limited to a chassis.
