## AI overview

This tutorial series explores routing protocol designs for EVPN-with-VXLAN Layer 2 VPNs in a leaf-and-spine data center fabric. It introduces a four-leaf, two-spine lab topology and begins with an OSPF-based IP fabric using VXLAN ingress replication without EVPN.

## Source excerpt

In this series of blog posts, we'll explore numerous routing protocol designs that can be used to implement EVPN-with-VXLAN L2VPNs in a leaf-and-spine data center fabric. Every design will come with a companion netlab topology you can use to create a lab and explore the behavior of leaf- and spine switches. Our leaf-and-spine fabric will have four leaves and two spines (but feel free to adjust the lab topology fabric parameters to build larger fabrics). The fabric will provide layer-2 connectivity to orange and blue VLANs. Two hosts will be connected to each VLAN to check end-to-end connectivity. Read more ...
