Claim 10:
11. A management apparatus in a hybrid cloud environment, wherein the hybrid cloud environment comprises a first data center and a second data center, the first data center is configured to provide a non-public cloud service, the second data center is configured to provide a public cloud service, a same private network segment is configured for a first subnet of the first data center and a second subnet of the second data center, and the management apparatus comprising a processor, a memory, and a communications interface, wherein the memory is configured to store computer-executable instructions, and when the management apparatus operates, the processor runs the computer-executable instructions in the memory to:
create a gateway, wherein the gateway is located in the second data center, the gateway is remotely connected to the first subnet of the first data center through a communication tunnel, and the gateway is connected to the second subnet of the second data center;
configure the gateway to intercept a first address resolution protocol ARP request packet that is from a first device in the first subnet and that is for a second device in the second subnet, and return a first ARP reply packet to the first device, wherein the first ARP reply packet carries a first MAC address of the gateway; and
configure the gateway to store a correspondence, carried in the first ARP request packet, between an IP address of the first device and a MAC address of the first device.
