Abstract:
1. A method for routing data packets in a routing device connecting a first network and a second network, said routing device comprising as separate components: a switch, and an integrated chipset including a bridge function, and a central processing unit (CPU) having a multicast group management module embedded therein, said method comprising the steps of: (a) receiving a frame, by a port of said switch, from a device connected to the first network; (b) forwarding the received frame to said bridge function; wherein the bridge function is performed by a means for forwarding a frame based on a destination address of the received frame; (c) checking, by the switch, whether the received frame contains a multicast group management message and in the affirmative, creating a new frame comprising a destination address of said multicast group management module and as payload at least multicast group management information extracted from the received frame; and (d) forwarding said new frame to the bridge function for transmission of the new frame to the multicast group management module to update multicast group information for the routing device.
