BGP is vastly superior to any L2 make-believe trash you can imagine, and amazingly, it often has better hardware offloading support for forwarding and firewalls. For example, 100G switches (L3+) like MikroTik's CRS504 do not support IPv6 in hardware for VXLAN-encapsulated flows, but everything just works if you choose to go the BGP route.

L2 is a total waste of time.
