Abstract
A system, device, and method for reducing the number of multicast routes maintained in a multicast routing information base aggregates a group of multicast routes and installs a single policy route for the group of multicast routes. The policy route is utilized as a default multicast route when no more-specific multicast route is available for one of the aggregated multicast routes. The policy routes are collected and distributed by a bootstrap device, preferably using a special bootstrap message.
