# [Demo] SONiC VPP L3 BGP

A small lab that brings up two [SONiC](https://sonicfoundation.dev/) with [FD.io VPP](fd.io) routers, configures basic BGP on each via [FRR](https://docs.frrouting.org/projects/dev-guide/en/latest/vtysh.html), and connects two Linux PCs to verify end‑to‑end L3 connectivity. This scenario extends [the simpler L3-only demo](https://github.com/PANTHEONtech/cnf-examples/tree/master/sonic-vpp/sonic-vpp-L3) by adding BGP peering and route advertisement.

## Prerequisites
- This example was successfully replicated on an Ubuntu (24.04.2 LTS) WSL instance in Windows.
- [Docker](https://docs.docker.com/engine/install/)
- [ContainerLab](https://containerlab.dev/install/)
- [sshpass](https://www.cyberciti.biz/faq/noninteractive-shell-script-ssh-password-provider/)

First, clone the repository so you have a local copy:

```bash
git clone https://github.com/PANTHEONtech/cnf-examples.git
```

To launch the example, simply execute the *run.sh* script within the folder you downloaded the example to:

```bash
./run.sh
