# Paragon Automation - Deploy L3VPN

## Overview

Paragon Automation is a Network automation platform and simplifies adoption of Network automation for device , network and service life cycles . The idea of Paragon is to eliminate repetitive tasks , improve operation efficiency.

This is a hands-on lab for Paragon Automation use cases Device LCM and Observability, L3VPN Orchestration, PAA, complex config templates .

This lab is based on Paragon Automation 2.0 features and the objective is to get hands on experience on these use cases . The platform will be preinstalled and preconfigured to start with specific use cases. We will be using vMX devices along with PA2.0

## Starting Lab

This lab allows for 16ppl (4ppl per sandbox) to take this lab persession.

If you would like to do this lab raise your hand to get Lab User information.

### Lab Blueprint Topology

The blueprint consists of four sets of vMX devices with traffic agents (TA’s), SET A, B, C and D. Also, a standalone shared ACX7100. Please note that you must choose the right SET of devices allocated to you.

We also have a Paragon Automation 2.0 on-prem instance installed with all device sets on-boarded.
