Description

Virtual Extensible LAN (VXLAN) is an overlay technology for network virtualization. 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.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.The initial IETF VXLAN standards defined a multicast-based flood-and-learn VXLAN without a control plane. It relies on data-driven flood-and-learn behavior for remote VXLAN tunnel endpoint (VTEP) peer discovery and remote end-host learning. 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. Flooding in such a deployment can present a challenge for the scalability of the solution. 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.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. MP-BGP EVPN has been defined by IETF as the standards-based control plane for VXLAN overlays. 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. 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.
