Abstract
In an embodiment, a method includes receiving an address-resolution-protocol (ARP) request at a first edge device from a first host device, advertising a first remote route associated with a first flag indicating the first edge device operates in a layer-3 optimized integrated-routing-and-bridging (IRB) mode by the first edge device based on the ARP request, receiving the first remote route at a second edge device from the first edge device, responsive to detecting the first flag by the second edge device, installing the first remote route into a layer-2 routing information base (RIB) associated with the second edge device.
