Ethernet virtual private network (EVPN)

An Ethernet virtual private network (EVPN) is made up of a set of CE devices that are connected to PE devices or MPLS Edge Switches (MES) that comprise the edge of the MPLS network. The CE devices could be hosts, routers, or switches. The MESs provide Layer 2 virtual bridge connectivity between the CE devices. You can deploy multiple EVPNs in the provider's network. In an EVPN, learning between MESs takes place in the control plane using BGP rather than in the data plane (as is the case with traditional bridging). EVPNs could be used to provide connectivity between data centers spanning Metropolitan Area Networks (MANs) and Wide Area Networks (WANs).
