Abstract
In a multicast control method, when an SSID or a BSSID of a specified VAP that will be delivered to an access point AP enables a multicast control function, an AC sends to the AP a CAPWAP multicast control message that includes multicast control enabling information, so that the AP creates a multicast control table according to the CAPWAP multicast control message that includes the multicast control enabling information and performs multicast control according to the multicast control table. With the method, the AC is responsible for delivering a multicast control policy to the AP, and the AP implements multicast replication and WLAN station rights control, which relieves the multicast control and multicast replication pressure on the AC effectively, improves the utilization of the network bandwidth, and overcomes the operator's difficulties in meeting multicast service requirements in the WLAN thoroughly.
