## AI overview

This tutorial explains how to scale an IBGP-based EVPN leaf-and-spine fabric by using spine switches as BGP route reflectors. It discusses placement considerations, interoperability and control-plane limits, then demonstrates the design with a netlab lab topology and optional GitHub Codespaces support.

## Source excerpt

In the previous blog posts, we explored the simplest possible IBGP-based EVPN design and tried to figure out whether BGP route reflectors do more harm than good. Ignoring that tiny detail for the moment, let's see how we could add route reflectors to our leaf-and-spine fabric. As before, this is the fabric we're working with: Read more ...
