Abstract
In one embodiment, a system includes a switch controller in communication with a plurality of switches in a switch cluster via a communication protocol. The switch controller includes a processor and logic integrated with and/or executable by the processor. The logic is configured to cause the processor to receive an address resolution protocol (ARP) request packet as a unicast packet from an entry switch in the switch cluster, the entry switch being connected to a first host. The logic is also configured to cause the processor to send an ARP response packet as a unicast packet to the entry switch. The ARP response packet indicates a media access control (MAC) address of the switch controller as a source MAC (SMAC) for the ARP response packet, and an internet protocol (IP) address of a virtual router of the switch controller as being a source of the ARP response packet.
