Abstract
A network device receives multicast packets that include information identifying destinations in the network, identifies next hops associated with the destinations, and populates a cache with the destinations and addresses of the identified next hops. The network device receives a particular multicast packet that includes information identifying particular destinations included in the cache, identifies one or more next hops for the particular destinations from the cache, and forwards the particular multicast packet to the identified one or more next hops to permit the identified one or more next hops to forward the multicast packet toward the particular destinations.
