1、MSR系列路由器PIM-SM功能的典型配置關(guān)鍵詞：MSR;PIM-SM;IGMP;組播；一、組網(wǎng)需求：RTA的端口E0/1連接組播源，端口S0/1連接RTB,端口S0/2連接RTC,分別在端口上啟PIM-SM組播協(xié)議；RTB的端口S0/2連接RTA,端口S0/1連接RTC,端口E0/1連接接受主機(jī)Received,分別在端口上啟PIM-SM組播協(xié)議,連接接受主機(jī)端口起IGMP
2、辦議；RTC的端口S0/1連接RTA,端口S0/2連接RTB,端口E0/1連接接受主機(jī)Receiverl,分別在端口上啟PIM-SM組播協(xié)議,連接接受主機(jī)端口起IGMP協(xié)議。設(shè)備清單
