Juniper Collapsed Spine with EVPN
Goal
In this tutorial, We will be setting up a collapsed Spine EVPN/VXLAN with multi-homing.We will use two SRX's in cluster mode to route traffic between the 2 Tenants that we will configure. We will be using BGP for the underlay and overlay.
Prerequisites
For this tutorial we will be using:
- EVE-NG 2.0.3-112
- VQFX model: vqfx-10000 running JUNOS 19.4R1.10 for spines and leaves
- VSRX 3.0
- Debian VM's servers
