Abstract: In one embodiment, a method includes receiving a packet from a first host at a first edge device, the packet comprising a layer 3 address of a second host in communication with a second edge device, using the layer 3 address of the second host to receive a layer 2 address and a location identifier for the second host from a database accessible from a core network, the database comprising a mapping of layer 3 host addresses to layer 2 host addresses and location identifiers, and storing a mapping of the layer 2 address to the location identifier at the first edge device for use in forwarding packets to the second host. The first edge device is in communication with the second edge device in an overlay network defined by the edge devices interconnected by the core network. An apparatus and logic are also disclosed herein.
