Abstract: A method for sending a multicast packet and a switch. A first switch receives a multicast packet from a first customer edge or a second customer edge, where the first customer edge is connected to the first switch in a single-homed manner, and the second customer edge is connected, in an all-active manner, to N switches that include the first switch; the first switch determines a specified multicast tree of the first switch; the first switch encapsulate the multicast packet, where a destination switch unique identification address in a header of the encapsulated multicast packet is a unique identification address of a root of the specified multicast tree of the first switch; and the first switch forwards the encapsulated multicast packet to a network side using the specified multicast tree of the first switch.

Abstract translation: 一种发送组播报文和交换机的方法。 第一交换机从第一客户边缘或第二客户边缘接收多播分组，其中第一客户边缘以单一归属方式连接到第一交换机，并且第二客户边缘以全部活动的方式连接 到包括第一开关的N个开关; 第一交换机确定第一交换机的指定组播树; 第一交换机封装组播报文，其中封装的组播报文头中的目的交换机唯一标识地址是第一交换机指定组播树根的唯一标识地址; 并且第一交换机使用第一交换机的指定的多播树将封装的组播分组转发到网络侧。
