It provides control-plane and data-plane separation and a unified control plane for both Layer-2 and Layer-3 forwarding in a VXLAN overlay network. It introduces control-plane learning for end hosts behind remote VTEPs. In this mode, end-host information learning and VTEP discovery are both data plane driven, with no control protocol to distribute end-host reachability information among VTEPs.

Prior to EVPN, VXLAN overlay networks operated in the flood-and-learn mode. MP-BGP EVPN is a control protocol for VXLAN based on industry standards.

VXLAN Overview: Cisco Nexus ® 9000 Series Switches.For more information about VXLAN and VXLAN with multicast-based flood-and-learn, please refer to the following documents: This document does not discuss the fundamentals of VXLAN, VXLAN in multicast-based flood-and-learn mode, or related network design options.

This document discusses the functions and configuration of MP-BGP EVPN and describes typical VXLAN overlay network designs using MP-BGP EVPN. The MP-BGP EVPN control plane introduces a set of features that reduces or eliminates traffic flooding in the overlay network and enables optimal forwarding for both west-east and south-north traffic. The MP-BGP EVPN control plane provides protocol-based VTEP peer discovery and end-host reachability information distribution that allows more scalable VXLAN overlay network designs suitable for private and public clouds. MP-BGP EVPN has been defined by IETF as the standards-based control plane for VXLAN overlays. To overcome the limitations of the flood-and-learn VXLAN as defined in RFC 7348, organizations can use Multiprotocol Border Gateway Protocol Ethernet Virtual Private Network (MP-BGP EVPN) as the control plane for VXLAN. The requirement to enable multicast capabilities in the underlay network also presents a challenge because some organizations do not want to enable multicast in their data centers or WAN networks. Flooding in such a deployment can present a challenge for the scalability of the solution. The overlay broadcast, unknown unicast, and multicast traffic is encapsulated into multicast VXLAN packets and transported to remote VTEP switches through the underlay multicast forwarding. It relies on data-driven flood-and-learn behavior for remote VXLAN tunnel endpoint (VTEP) peer discovery and remote end-host learning. The initial IETF VXLAN standards (RFC 7348) defined a multicast-based flood-and-learn VXLAN without a control plane. The purpose of obtaining Layer-2 extension in the overlay network is to overcome the limitations of physical server racks and geographical location boundaries and achieve flexibility for workload placement within a data center or between different data centers.

It provides Layer-2 extension over a shared Layer-3 underlay infrastructure network by using MAC address in IP User Datagram Protocol (MAC in IP/UDP) tunneling encapsulation.
