1  簡介

本文檔介紹PIM-SM C-BSR和C-RP功能的配置。

2  配置前提

本文檔不嚴格與具體軟、硬件版本對應，如果使用過程中與產品實際情況有差異，請參考相關產品手冊，或以設備實際情況為準。

本文檔中的配置均是在實驗室環境下進行的配置和驗證，配置前設備的所有參數均采用出廠時的缺省配置。如果您已經對設備進行了配置，為了保證配置效果，請確認現有配置和以下舉例中的配置不衝突。

本文檔假設您已了解PIM-SM特性。

3  配置舉例

3.1  組網需求

如圖1所示，Router A連接組播源，Router B和Router C各連接一台組播接收者，三台MSR設備兩兩相連。

現要求通過配置PIM SM實現：

·     組播接收者收到組播源發送的組播組；

·     PIM SM的C-BSR和C-RP功能。

圖1 PIM-SM配置組網圖

設備	接口	IP地址	設備	接口	IP地址
Router A	Eth0/0	192.168.0.1/24	Router C	Eth0/0	192.168.0.2/24
	Eth0/1	10.0.1.1/24		Eth0/1	192.168.2.2/24
	Eth0/2	192.168.1.1/24		Eth0/2	10.0.3.1/24
Router B	Eth0/0	192.168.1.2/24	Host A		10.0.2.2/24
	Eth0/1	192.168.2.1/24	Host B		10.0.3.2/24
	Eth0/2	10.0.2.1/24	Source		10.0.1.2/24

 

3.2  配置思路

·     各路由器使能OSPF，使各路由器之間能夠借助單播路由協議實現動態路由更新。

·     為使組播接收者接收組播數據全局啟動組播，配置C-BSR與C-RP，並在連接組播接收者的路由器接口使能IGMP。

3.3  使用版本

本舉例是在Release 2317版本上進行配置和驗證的。

3.4  配置注意事項

·     配置PIM-SM域內的各路由器之間采用OSPF協議進行互連，確保PIM-SM域中Router A、Router B、Router C之間能夠在網絡層互通，並且各路由器之間能夠借助單播路由協議實現動態路由更新；

·     在連接末梢網絡的接口使能IGMP協議。
