Goal

In this tutorial we are going to setup 2 sites: Site A and site B and connect both sites together using a MPLS backbone. Both sites will be configured using EVPN-VXLAN centrally Routed Bridging (CRB).

Prerequisites

For this tutorial I will be using :

- EVE-NG 2.0.3-112

- VQFX model: vqfx-10000 running JUNOS 19.4R1.10 for spines and leaves

- VMX running Junos: 18.2R1.9 for the core routers

- Debian VM's servers
