Abstract
A first network device adapted for communication with one or more other network devices is configured to determine a number of receivers of a multicast, and to control switching of traffic between selective and inclusive routes for the multicast based at least in part on the determined number of receivers. For example, in some embodiments the first network device is configured to control switching of traffic between the selective and inclusive routes for the multicast by utilizing a selective route for the multicast responsive to a determination that traffic for the multicast is at or above a bandwidth threshold and the number of receivers is below an add threshold, and utilizing an inclusive route for the multicast responsive to a determination that traffic for the multicast is below the bandwidth threshold or the number of receivers is above a delete threshold.
