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
