3. 使能组播路由功能，并配置PIM-SM功能
[LSW1]multicast routing-enable
[LSW1-Vlanif10]pim sm
[LSW1-Vlanif100]pim sm
[LSW2]multicast routing-enable
[LSW2-Vlanif20]pim sm

[LSW3]multicast routing-enable
[LSW3-Vlanif10]pim sm
[LSW3-Vlanif30]pim sm
[LSW3-Vlanif300]pim sm
[LSW4]multicast routing-enable
[LSW4-Vlanif20]pim sm
[LSW4-Vlanif40]pim sm
[LSW4-Vlanif400]pim sm
[LSW5]multicast routing-enable
[LSW5-Vlanif30]pim sm
[LSW5-Vlanif40]pim sm
4. 在主机侧接口使能IGMP功能
[LSW3-Vlanif300]igmp enable
[LSW4-Vlanif400]igmp enable
5. 配置C-BSR、C-RP的位置
[LSW3-LoopBack1]pim sm
[LSW3-LoopBack10]pim sm
[LSW3]pim
[LSW3-pim]c-bsr LoopBack 1
[LSW3-pim]c-rp LoopBack 10
[LSW4-LoopBack1]pim sm
[LSW4-LoopBack10]pim sm
[LSW4]pim
[LSW4-pim]c-bsr LoopBack 1
[LSW4-pim]c-rp LoopBack 10
6. 配置MSDP对等体
[LSW3-LoopBack0]pim sm
[LSW3]msdp
[LSW3-msdp]originating-rp LoopBack 0
[LSW3-msdp]peer 10.2.2.2 connect-interface LoopBack 0
[LSW4-LoopBack0]pim sm
[LSW4]msdp
[LSW4-msdp]originating-rp LoopBack 0
[LSW4-msdp]peer 10.5.5.5 connect-interface LoopBack 0
7. 验证配置
PIM-SM域内组播源MCS1向组播组G（225.1.1.1）发送组播信息，用户PC1加入组播组G，接收发往组G的组播数据,通过比较LSW3和LSW4上PIM路由的显示信息，可知当前有效RP是LSW3：MCS1向LSW3注册，PC1向LSW3发起加入
PC1退出组播组G，MCS1停止向组播组G发送组播数据,使用命令LSW3上的组播路由表项和转发表项
<LSW3>reset multicast routing-table all
<LSW3>reset multicast forwarding-table all
用户PC2加入组播组G，MCS2开始向组播组G发送组播数据,通过比较LSW3和LSW4上PIM路由的显示信息，可知当前有效RP是LSW4：MCS2向LSW4注册，PC2向LSW4发起加入
