摘要： A first network device adapted for communication with one or more other network devices is configured to originate a first route identifying a tunnel for carrying traffic for a multicast, to originate a second route specifying a leaf information requirement for the multicast but not identifying a tunnel for carrying traffic for the multicast, and to track a plurality of receivers of the multicast based at least in part on leaf information received from the multicast receivers responsive to the specified leaf information requirement of the second route. The first route may comprise an inclusive route having a tunnel attribute that identifies an inclusive tunnel for the multicast and the second route may comprise a selective route having a tunnel attribute configured to indicate that it carries no tunnel information. Multicast traffic can be switched between an inclusive tunnel and a selective tunnel responsive to the multicast receiver tracking.

摘要翻译：适用于与一个或多个其他网络设备进行通信的第一网络设备被配置为发起标识用于承载多播的业务的隧道的第一路由以发起指定多播的叶信息要求但不标识用于多播的隧道的第二路由承载多播的业务，并且响应于第二路由的指定叶信息要求，至少部分地基于从多播接收器接收的叶信息来跟踪多播的多个接收器。第一路由可以包括具有隧道属性的包含性路由，该隧道属性标识用于多播的包含性隧道，并且第二路由可以包括具有隧道属性的选择性路由，该路由属性被配置为指示其不携带隧道信息。响应于多播接收机跟踪，多播业务可以在包含性隧道和选择性隧道之间切换。
