VXLAN-EVPN Lab with ContainerLab

Sources

• ContainerLab
• Virtual Data Center Network

Overview

This project provides a hands-on lab environment for understanding and experimenting with VXLAN-EVPN (Ethernet VPN) technology. Using ContainerLab, the lab sets up a VXLAN topology featuring 1 spine and 2 leaves nodes. The lab can be deployed directly on a PC with ContainerLab installed or through a DevContainer environment.

Project Structure

The project directory is structured as follows:

• hosts: Directory containing host configuration files for the lab.
• network_images/ceos-lab-4.32.0.1F.tar.xz: Container image used for the lab nodes.
• lab_vxlan.yml: YAML file describing the VXLAN lab topology.

Prerequisites

• Docker and Docker Compose (for DevContainer setup).
• ContainerLab installed either on the host or within the DevContainer.
• Basic understanding of networking and VXLAN-EVPN concepts.

Setup and Deployment

1. DevContainer Setup (Optional):
   If using DevContainer, ensure Docker and Docker Compose are installed on your machine.
   Open the project in a compatible IDE (like Visual Studio Code) and start the DevContainer environment.

2. ContainerLab Setup:

   • Direct Installation: Install ContainerLab on your host machine.
   • Via Terraform, documentation avalaible here

3. Start the Lab:

   • Navigate to the project directory.
   • Add Arista image to Docker docker import network_images/cEOS64-lab-4.32.0.1F.tar.xz ceos:4.32.0.1F
   • Run sudo containerlab deploy -t lab_vxlan.yml to deploy the lab topology.

Usage

• Once the lab is deployed, you can access the individual nodes (spines and leaves) via CLI or SSH to configure and test VXLAN-EVPN functionalities.
• Use the hosts directory to modify or apply specific configurations.

Known Issues

On Alpine Linux hosts 1 and 2, it is necessary to install the vlan package:

apk add vlan
