A system, device, and method for reducing the number of multicast routesmaintained in a multicast routing information base aggregates a group ofmulticast routesand installs a single policy route for the group of multicast routes. Thepolicy route isutilized as a default multicast route when no more-specific multicast route isavailable forone of the aggregated multicast routes. The policy routes are collected anddistributed by abootstrap device, preferably using a special bootstrap message.
