While the aforementioned will give you some good material, they focus mainly on the building of Clos based leaf-spine fabric for connectivity within a single data centre. And there's a reason for that.
Cisco are not proposing MP-BGP and EVPN as a data centre interconnect at this stage as all the required features are not yet implemented. Note in particular slide 108 in the BRKDCT-3378 presentation.
Taken from that slide:
VXLAN applicability evolves as the Control Plane evolves!
Yesterday: VXLAN, yet another Overlay
Data-Plane only (Multicast based Flood & Learn)
Today: VXLAN for the creation of scalable DC Fabrics – Intra-DC
Control-Plane, active VTEP discovery, Multicast and Unicast (Head-End Replication)
