A method, an apparatus, and a system for controlling sending of a MAC address forwarding table are provided. In the solution, when it is determined that a destination IP address is different from any IP address of a gateway to which a source virtual machine is attached, generation, according to an ARP request packet, a first MAC address forwarding table that is to be sent to the gateway is forbidden; and when it is determined that IP addresses of the gateway to which the source virtual machine is attached include an IP address that is the same as the destination IP address, a first MAC address forwarding table that is to be sent to the gateway is generated according to the ARP request packet, and the first MAC address forwarding table is sent to the gateway.

Method, apparatus, and system for controlling sending of MAC address forwarding table

Embodiments provide a packet forwarding method and a network device, which are applicable to a system that includes a source node, a destination node, a first device, and a second device, where L, L, Land Lare established, and the packet forwarding method includes: receiving, by the second device through a universal tunnel, a packet to be sent to a destination node, where the packet carries service data and one of identifiers of the L, the L, the L, and the L; according to the identifier carried in the packet, querying a preconfigured logical channel mapping in the second device, determining that a forwarding channel is the L, and sending the service data in the packet to the destination node through the L. By using the technical solutions, the number of ICB PWs can be reduced.
