Ethernet VPN (EVPN) is a technology for carrying layer 2 Ethernet traffic as a virtual private network using wide area network protocols. EVPN technologies include Ethernet over MPLS and Ethernet over VXLAN.^[1][2]

EVPNs are covered by a number of Internet RFCs, including:

• RFC 7209 "Requirements for Ethernet VPN (EVPN)",
• RFC 7432 "BGP MPLS-Based Ethernet VPN",
• RFC 8365 "A Network Virtualization Overlay Solution Using Ethernet VPN (EVPN)",
• RFC 8317 "Ethernet-Tree (E-Tree) Support in Ethernet VPN (EVPN) and Provider Backbone Bridging EVPN (PBB-EVPN)".
• RFC 9161 "Operational Aspects of Proxy ARP/ND in Ethernet Virtual Private Networks".
