Dmitry Klepcha published an excellent document describing how you can use netlab to build a series of data center fabric labs, starting from a simple IP network (without routing) and finishing with a complex EVPN/VXLAN network using symmetric IRB and MLAG toward hosts.

But wait, there’s more: all the lab topologies he used in his exercises are available on GitHub, which means that you could just clone the repo and start using them (I also “borrowed” some of his ideas as future netlab improvements).

Finally, thanks a million to Roman Pomazanov for bringing Dmitry’s work to my attention (and for the quote at the end of his post ;).
