Abstract
A method for multicast packet forwarding in a switch. The switch includes a look-up table and a plurality of ports. The switch transfers a multicast packet according to the look-up table. The method includes receiving the multicast packet from a port; if the multicast packet conforms to a specific transmission protocol then detecting a destination address information in the multicast packet; and checking whether the destination address information belongs to a network address set, wherein if the destination address information belongs to the network set the port is determined to be coupled to a multicast packet processing device and a corresponding relationship between the port and the multicast packet processing device is stored into the look-up table.
