Claim of US Patent No. 9,509,527

1. A method for virtual extensible local area network (VXLAN) encapsulation, comprising:
receiving a first augmented media access control (MAC) frame on a first ingress port of a first network device, wherein the
first augmented MAC frame comprises a first egress port ID (EPID), a first ingress port ID (IPID), and a first MAC frame;

identifying a first destination VXLAN tunnel endpoint (VTEP) internet protocol (IP) address based on the first EPID, wherein
the first destination VTEP IP address is associated with a first destination VTEP;

identifying a source VTEP IP address based on the first IPID;
performing VXLAN encapsulation of the first MAC frame to obtain a VXLAN frame, wherein the first VXLAN frame comprises the
source VTEP IP address, the first destination VTEP IP address and the first MAC frame; and

sending the VXLAN frame to the first destination VTEP via a first egress port of the first network device.
