1  简介

本文档介绍使用Embedded RP的典型案例。

2  配置前提

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Embedded RP的特性。

3  配置举例

3.1  组网需求

如图1所示，在IPv6网络中，Router A、Router B、Router C和Router D运行OSPFv3协议，单播路由可达。所有路由器运行PIM SM组播路由协议，并缺省情况下支持嵌入式RP解析功能。Router D运行MLD协议。现要求：在组播源Server上使用嵌入式RP功能直接指定某组播组对应的RP地址，实现组播数据的转发。

图1 MSR路由器Embedded RP基本组网图

3.2  配置思路

为了使Receiver接受到组播源的组播报文，需要在Router D接口配置静态路由加入IPv6组播源组，同时保证该接口使能MLD。

3.3  使用版本

本举例是在Release 2311版本上进行配置和验证的。
