Abstract: A network device creates a forwarding table that includes information associated with a set of destinations in a network, and determines next hops for the set of destinations. The network device populates the forwarding table with information associated with the next hops, and stores the forwarding table. The forwarding table is used to forward a multicast packet toward a multiple destinations, and includes separate entries that depend upon routes the multicast packet is to traverse towards destinations with multiple choices for next hops.

Abstract: A network device creates multiple forwarding tables, and each forwarding table includes information associated with a first set of destinations and a second set of destinations. The first set of destinations is different than the second set of destinations. The network device determines, for each forwarding table, next hops for the first set of destinations, and determines, for each forwarding table, equal cost multipath next hops for the second set of destinations. The network device populates the multiple forwarding tables with information associated with the next hops and the equal cost multipath next hops, and the multiple forwarding tables are used to forward a multicast packet toward multiple destinations.

Abstract translation: 网络设备创建多个转发表，并且每个转发表包括与第一组目的地和第二组目的地相关联的信息。 第一组目的地与第二组目的地不同。 网络设备为每个转发表确定第一组目的地的下一跳，并且为每个转发表确定第二组目的地的相同的成本多路径下一跳。 网络设备使用与下一跳相关联的信息和等价多路径下一跳来填充多个转发表，并且使用多个转发表将多播分组转发到多个目的地。
