Claim of US Patent No. 9,866,409

1. A method for virtual extensible local area network (VXLAN) decapsulation, comprising:
receiving a VXLAN frame on a first ingress port of a first network device, wherein the VXLAN frame comprises a source VXLAN
tunnel endpoint (VTEP) internet protocol (IP) address, a destination VTEP IP address, a VXLAN network identifier (VNI), and
a media access control (MAC) frame;

identifying an egress port ID (EPID) based on the destination VTEP IP address, wherein the destination VTEP IP address is
associated with a destination VTEP;

determining that the destination VTEP is located on the first network device;
identifying an ingress port ID (IPID) based on the source VTEP IP address, wherein the source VTEP IP address is associated
with a source VTEP;

generating an augmented MAC frame, wherein the augmented MAC frame comprises the IPID, the EPID, the VNI, and the MAC frame,
and wherein the MAC frame comprises a destination host MAC address;

identifying an egress port on the first network device based on the EPID; and
sending the augmented MAC frame to a second network device via the egress port on the first network device.
