Claim of US Patent No. 10,216,853

1. A method for distributing virtual extensible local area network (VXLAN) configuration information in a multi-tier network, the method comprising:receiving first VXLAN configuration information, by an intermediate network device database client, executing on an intermediate network device in an intermediate tier of the multi-tier network, from a first leaf network device database server executing on a first leaf network device,
wherein the first VXLAN configuration information is generated by a virtual tunnel endpoint (VTEP) that is operatively connected to the first leaf network device, and
wherein the first VXLAN configuration information comprises a VTEP Internet Protocol (IP) address to Media Access Control (MAC) address mapping;
comparing a first timestamp associated with the first VXLAN configuration information with second timestamp of a first database entry to make a determination that the VXLAN configuration information is newer than the first database entry;
discarding the first database entry based on the determination;
storing, after discarding the first database entry, the first VXLAN configuration information in a second database entry in an intermediate network device database on the intermediate network device;
sending a first copy of the second database entry, by the intermediate network device database client, to a root network device; and
sending a second copy of the second database entry, by the intermediate network device database client, to a second leaf network device database server that is executing on a second leaf network device.
