EVPN is one of the major reasons we’re seeing BGP used in small- and mid-sized data center fabrics. In theory, EVPN is just a BGP address family and shouldn’t have an impact on your BGP design. In practice, suboptimal implementations might invalidate that assumption.
I've described a few EVPN-related BGP gotchas in BGP in EVPN-Based Data Center Fabrics, a section of Using BGP in Data Center Leaf-and-Spine Fabrics article.
Alex raised a number of valid points in his comments to this blog post. While they don't fundamentally change my view on the subject, they do warrant a more nuanced description. Expect an updated version of this part of the article when I return from Cisco Live Europe

The flexibility of cloud infrastructure has had a significant impact on the way that organizations build out their infrastructure, but the industry is continuing to learn just how complicated connecting to cloud resources can be. In this episode of Network Collective we take a look at the challenges around cloud connectivity and talk about some ways to do it well.

A while back I posted on section 10 routing loops; Daniel responded to the post with this comment:
I am curious how these things are discovered. You said that this is a contrived example, but I assume researchers have some sort of methodology to discover issues like this. I am sure some things have been found through operational mishap, but is there some “standardized” way of testing graph logic for the possibility of loops? I trust this is much easier to do today than even a decade ago.
You would think there would be some organized way to discover these kinds of routing loops, something every researcher and/or protocol designer might follow. The reality is far different—there is no systematic way that I know of to find this sort of problem. What happens, in real life, is that people with a lot of experience at the intersection of protocol design, the bounds of different ways of finding loop free paths (solving the loop free path problem), and a lot of experience in deploying and operating a network using these protocols, will figure these things out because they know enough about the solution space to look for them in the first Continue reading
