EVPN control plane for VXLAN supported interfaces

Traditionally, data centers have used Layer 2 technologies such as Spanning Tree Protocol (STP), Multi-Chassis Link Aggregation Group (MC-LAG), or TRILL for compute and storage connectivity. As the design of data centers shifts from more traditional to scale-out, service-oriented multitenant networks, a new data center architecture has been provided that allows decoupling of an underlay network from the tenant overlay network with VXLAN. By using a Layer 3 IP-based underlay coupled with a VXLAN-EVPN overlay, you can deploy larger networks than those possible with traditional Layer 2 Ethernet-based architectures. With overlays, end points (servers or virtual machines) can be placed anywhere in the network and remain connected to the same logical Layer 2 network.
