Abstract: Systems, methods and computer-readable storage media are provided for performing Internet Protocol (IP) address resolution within a network through a control plane or network controller approach. A provider edge (PE) device receives an Address Resolution Protocol (ARP) request message from a locally connected customer edge (CE) device. The PE device transmits the ARP request message to other locally connected CE devices and generates an IP address resolution request message that includes the IP address of a destination CE device. The IP address resolution request message is transmitted to other PE devices within the network. The PE device receives remote adjacency information associated with the destination CE device and transmits an ARP reply message to the locally connected CE device.
