US Patent 11184276 EVPN signaling using segment routing

A node in a Segment Routing network includes a plurality of ports and a switching fabric between the plurality of ports, wherein, for an Ethernet Virtual Private Network (EVPN)-Virtual Private Local Area Network Service (VPLS), a port is configured to transmit a packet with a plurality of Segment Identifiers (SID) including a destination SID that identifies a destination node of the packet, a service SID that identifies an EVPN Instance (EVI), and a source SID that identifies one of the node and an Ethernet Segment (ES) that includes the node. The port can be further configured to receive a second packet with a second plurality of SIDs, and learn a Media Access Control (MAC) address based on a second service SID and a second source SID, of the second packet.
