# VXLAN-EVPN Lab with ContainerLab

## 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:

- `.devcontainer/devcontainer.json`: Configuration for the DevContainer environment.
- `hosts`: Directory containing host configuration files for the lab.
- `network_images/ceos-lab-4.30.3M.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 DevContainer: Use the provided `devcontainer.json` to set up a ContainerLab environment.

3. **Start the Lab:**
   - Navigate to the project directory.
   - Run `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.
