Abstract: In one example, a method includes exchanging, by a first routing device and with a second routing device, targeted hello messages using a Protocol Independent Multicast (PIM) protocol to establish a targeted neighbor connection between the first routing device and the second routing device, wherein the first routing device exchanges the targeted hello messages with the second routing device via at least one intermediate routing device, and wherein at least one of the first or second routing device comprises a rendezvous point (RP). The example method further includes processing, by the first routing device using the targeted neighbor connection, a register message that includes multicast stream data elements, wherein each multicast stream data element identifies a source address and a group address that are collectively associated with a respective multicast stream, and wherein each multicast stream data element further indicates whether the respective multicast stream is active or withdrawn.

Abstract translation: 在一个示例中，一种方法包括由第一路由设备和第二路由设备使用协议独立组播（PIM）协议来交换目标的hello消息，以在第一路由设备和第二路由设备之间建立目标邻居连接， 其中所述第一路由设备经由至少一个中间路由设备与所述第二路由设备交换目标的hello消息，并且其中所述第一或第二路由设备中的至少一个包括会合点（RP）。 所述示例性方法还包括由所述第一路由设备使用所述目标邻居连接来处理包括多播流数据元素的注册消息，其中每个多播流数据元素标识与相应多播合并关联的源地址和组地址 流，并且其中每个多播流数据元素进一步指示相应的多播流是活动还是撤销。
