Abstract

本发明提供一种虚拟专用局域网服务组播保护的方法及装置，其中，所述方法包括：在主用设备与数据报文发送端之间的链路出现故障后，备用设备接收来自所述数据报文发送端的数据报文，并将所述数据报文转发给所述主用设备，所述主用设备将来自所述备用设备的所述数据报文通过主用点到多点P2MP树转发给数据报文接收端。本发明还提供另一种虚拟专用局域网服务组播保护的方法及装置，所述方法包括：在主用设备出现故障之后，备用设备接收来自数据报文发送端的数据报文，并将所述数据报文通过备用P2MP树或者通过修剪的虚拟专用局域网服务VPLS网络转发给数据报文接收端。因此，本发明能对入口PE、及入口PE与CE之间的链路进行保护。
