  • System and method for resilient VPLS over multi-nodal APS protected provider edge nodes
    Publication number: 20070253326
    Abstract: A system and method for multi-nodal APS (MN-APS) protection switching for a virtual private LAN service (VPLS) using a redundant pair of PE (provider edge) nodes is provided. In the event of an APS switchover, the previously active node of the redundant pair sends explicit requests to the other provider edge nodes to flush their MAC address entries that they had previously learned through the previously active node, facilitating quicker re-convergence and reduction of black-holing.
