1. A method for synchronizing a route change in a routing table for a plurality of multicast routing protocols in a network device in a communication network device, the method comprising:

  • assigning a route ID value to each route in the routing table;

    assigning a bookmark in a route change queue to each multicast routing protocol, the bookmark having a value equivalent to the route ID value of the last route processed by the multicast routing protocol, wherein the route change queue is separate from the routing table, and wherein the route change queue is shared across the plurality of multicast routing protocols;

    assigning a new route ID value to each route changed in the routing table;

    independently storing each route changed in both the routing table and the route change queue; and

    comparing the bookmark value of each multicast routing protocol to the highest route ID value in the route change queue.
