  • METHOD, ACCESS LAYER DEVICE, AND SYSTEM FOR IMPLEMENTING MULTICAST IN RING NETWORK ARCHITECTURE
    Publication number: 20130003527
    Abstract: The present invention provides a method for implementing multicast in a ring network architecture. The ring network architecture includes a first aggregation layer device, a second aggregation layer device, a first access layer device connected to the first aggregation layer device, and a second access layer device connected to the second aggregation layer device. The first aggregation layer device is connected to the second aggregation layer device; the first access layer device is connected to the second access layer device. The method includes: setting the first access layer device and the second access layer device as root bridges; reducing a bridge priority of the first access layer device when a fault occurs on a link between the first aggregation layer device and the first access layer device, calculating a root port RP of the first access layer device through the STP, and sending a multicast Join packet through the RP.
