Arista Leaf Spine topology for L3 lab practice

eveng-arista-topology

This repository provides a topology file to build an Arista L3LS+EVPN fabric in EVE-NG. The fabric topology is meant to help with exploring and practicing concepts in Arista's EVPN Deployment Guide.

Requirements

To deploy the topology, you will need to have the following:

• a running instance of EVE-NG
• The evensdk library and CLI tool.

Note: The topology uses veos-4.27.0F for the node image. Make sure that you either have the image available by downloading from the Arista portal, or replace it with a veos image that you already have in EVE-NG.

Install Requirements

To install the evengsdk library and CLI tool, run the following command:

pip install eve-ng

Configure Your Environment

You can define your environment variables in a .env so that you can easily export environemnt variables to configure the EVE-NG CLI tool. This will prevent you from getting prompted for credentials.

STEP 1. Create your .env file

export EVE_NG_HOST=192.168.2.100
export EVE_NG_USERNAME=admin
export EVE_NG_PASSWORD=eve

⚠️ The .env file is ignored from version control so that you do not accidentally

STEP 2. Source the variables from the file

source .env

Create lab from topology

Create the lab

eve-ng lab create-from-topology -t topology.base.yml

Verify that lab is showing in list

eve-ng lab list

View the nodes in your lab

eve-ng node list --path /arista-level3-lab.unl

Note: To avoid repeatedly having to provide the lab path, you can export EVE_NG_LAB_PATH=/arista-level3-lab.unl or add it to your .env file and source it.

Start your lab

eve-ng lab start --path /arista-level3-lab.unl
