| 摘要 | In one embodiment, a method includes building an address resolution cache for a layer-3 router in a first layer-2 datacenter, where the address resolution cache includes a plurality of entries, each of the entries containing a host network address, a host hardware address, and a switch identifier for a switch serving a host, intercepting an address resolution flood within the first layer-2 datacenter that seeks address resolution for a host in a second layer-2 datacenter, and generating a response to the address resolution flood that indicates a source in the second layer-2 datacenter, where data indicating the source in the second layer-2 datacenter is accessed from the address resolution cache. | ||

| 主权项 | 1. A method comprising: performing the following actions in a layer-3 router in a first layer-2 datacenter: building an address resolution cache for the layer-3 router in the first layer-2 datacenter, where the address resolution cache includes a plurality of entries, each of the entries containing a host network address, a host hardware address, and a switch identifier for a switch serving a host; intercepting an address resolution flood within the first layer-2 datacenter that seeks address resolution for a host in a second layer-2 datacenter; and generating a response to the address resolution flood that indicates a source of the response is a switch in the second layer-2 datacenter, where data indicating the source in the second layer-2 datacenter is accessed from the address resolution cache. | ||
