This lab will enable a student to build a basic Multi-Site fabric using Apstra for complete end-to-end connectivity.

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.

There are many different ways to create an Arista-based VXLAN EVPN fabric; these 3 lab scenarios presents 1) a migration phase from a standard 3 tier VLAN and SVI-based network to a VXLAN fabric, 2) using Asymmetrical IRB and 3)Symmetrical IRB. BGP routing is the underlay, overlay, and connectivity to the remote data center under migration. This sandbox and configs can be further used to explore other configurations and functionality of Arista CVP.

Arista CloudVision provides a centralized, model-driven platform for deploying, managing, and extending VXLAN EVPN fabrics using Studios. In this hands-on lab, you will use CloudVision to build and operate a VXLAN EVPN leaf-spine fabric across multiple sites while maintaining consistent policies, visibility, and control. The lab begins with onboarding, switches into CloudVision, and assigns roles using Studios. You will then configure MLAG for high availability, set up VXLAN EVPN underlay and overlay parameters, and map VLANs to VNIs to enable multi-tenant segmentation and workload connectivity. Next, you will implement inter-VRF routing and route leaking using EVPN and BGP constructs. Finally, the lab extends the design into a VXLAN EVPN Multi-Site architecture, integrating multiple fabrics under a unified control and policy framework. This lab demonstrates how CloudVision and Studios simplify the deployment, operation, and lifecycle management of complex VXLAN EVPN fabrics, providing centralized visibility, consistent configuration, and scalable multi-site operations.

In a VXLAN fabric, the connection point to the VXLAN Fabric is the access layer, typically formed by the leaf switches. While the underlay provides the robust transport and the overlay delivers the virtual network services, it's the device connectivity to these leaf switches and the resiliency built into that access layer that directly impacts application uptime and user experience. A single point of failure at the access layer can bring down critical applications, negating all the benefits of a resilient spine/leaf underlay and a scalable VXLAN overlay. This lab guide, "Building Redundancy with vPC, MLAG, ESI, and eBGP Underlay Creation," is designed to provide you with hands-on experience in configuring and verifying resilient access layer connectivity in a multi-vendor VXLAN fabric. Look for part 2 of this series, where we dive into advanced VXLAN techniques such as flood and learn and MP-BGP EVPN
