目 录
本文档介绍PIM-SM C-BSR和C-RP功能的配置。
本文档不严格与具体软、硬件版本对应，如果使用过程中与产品实际情况有差异，请参考相关产品手册，或以设备实际情况为准。
本文档中的配置均是在实验室环境下进行的配置和验证，配置前设备的所有参数均采用出厂时的缺省配置。如果您已经对设备进行了配置，为了保证配置效果，请确认现有配置和以下举例中的配置不冲突。
本文档假设您已了解PIM-SM特性。
如图1所示，Router A连接组播源，Router B和Router C各连接一台组播接收者，三台MSR设备两两相连。
现要求通过配置PIM SM实现：
· 组播接收者收到组播源发送的组播组；
· PIM SM的C-BSR和C-RP功能。

· 各路由器使能OSPF，使各路由器之间能够借助单播路由协议实现动态路由更新。
· 为使组播接收者接收组播数据全局启动组播，配置C-BSR与C-RP，并在连接组播接收者的路由器接口使能IGMP。
本举例是在Release 2317版本上进行配置和验证的。
· 配置PIM-SM域内的各路由器之间采用OSPF协议进行互连，确保PIM-SM域中Router A、Router B、Router C之间能够在网络层互通，并且各路由器之间能够借助单播路由协议实现动态路由更新；
· 在连接末梢网络的接口使能IGMP协议。
