Goal

In this tutorial we will setup a spine/leaf topology with 2 spines and 2 leaves. The goal is to configure EVPN-VXLAN centrally Routed Bridging (CRB)

What is Centrally Routed Bridging?=

Centrally Routed Bridging( CRB) is just another mechanism that provides routing functionally within the EVPN-VXLAN fabric.

In the CRB design, the inter-VXLAN routing is performed by the spine devices.
