In reply to jean-christophe manciot.

Salut Jean-Christophe,
merci pour votre compliment.

VXLAN/EVPN is available today on Cisco Nexus 9300 in the NX-OS (Standalone) mode; ACI provides its own and integrated control-plane.
Predominantly, the Nexus 9500 is deployed in the Spine and hence does not require VTEP capabilities itself for participating in VXLAN networks (Spine is transparent Layer-3 forwarder). For the role of a BGP Route-Reflector, the Nexus 9500 does already support all requirements for MP-BGP EVPN.
Nexus 9500 is about to follow with VXLAN and VXLAN/EVPN capabilities going forward.
