EVPN/VXLAN or Bridged Data Center Fabric?

An attendee in the Building Next-Generation Data Center online course sent me an interesting dilemma:

Some customers don’t like EVPN because of complexity (it is required knowledge BGP, symmetric/asymmetric IRB, ARP suppression, VRF, RT/RD, etc). They agree, that EVPN gives more stability and broadcast traffic optimization, but still, it will not save DC from broadcast storms, because protections methods are the same for both solutions (minimize L2 segments, storm-control).

We’ll deal with the unnecessary EVPN-induced complexity some other time, today let’s start with a few intro-level details.
