Abstract: A data plane of a first network device receives a first packet sent by a multi-homing access device, sends the first packet to a control plane of the first network device, adds an MC-LAG identifier to the first packet to obtain a second packet, and sends the second packet to a data plane of a second network device through a data forwarding path. The control plane generates a forwarding entry according to an ingress port of the first packet on the first network device and the first packet, updates a first forwarding table on the control plane according to the forwarding entry, and sends the forwarding entry to the data plane of the first network device. The data plane of the first network device updates a second forwarding table on the data plane of the first network device according to the forwarding entry.
