Abstract: Embodiments of the present invention provide a method and an apparatus for forwarding multicast traffic. The method includes: receiving a third multicast join message; in response to the third multicast join message, sending a first multicast join message to a first upstream router, and establishing an active path; in response to the third multicast join message, sending a second multicast join message to a second upstream router, and establishing a standby path; and sending multicast traffic to the multicast receiver through the active path, where the standby path does not forward the multicast traffic. In the foregoing embodiments, the standby path that does not forward the multicast traffic is established beforehand, so that when a fault occurs in the active path, the standby path established beforehand can be used to forward the multicast traffic.

Abstract translation: 本发明的实施例提供了一种用于转发多播业务的方法和装置。 该方法包括：接收第三组播加入消息; 响应于所述第三组播加入消息，向第一上游路由器发送第一组播加入消息，并建立活动路径; 响应于所述第三组播加入消息，向第二上游路由器发送第二组播加入消息，并建立备用路径; 并通过主用路径向组播接收者发送组播流量，备用路径不转发组播流量。 在上述实施例中，预先建立不转发组播流量的备用路径，使得当在活动路径中发生故障时，预先建立的备用路径可以用于转发多播业务。
