3. 在所有交换机上使能组播功能，并在各接口上使能PIM-SM
[LSW1]multicast routing-enable
[LSW1-Vlanif10]pim sm
[LSW1-Vlanif20]pim sm
[LSW1-Vlanif30]pim sm
[LSW1-Vlanif100]pim sm
[LSW1-LoopBack0]pim sm
[LSW2]multicast routing-enable
[LSW2-Vlanif10]pim sm

[LSW5-Vlanif50]pim sm
[LSW5-Vlanif60]pim sm
[LSW5-Vlanif200]pim sm
4. 在所有交换机上将LSW1的Loopback0接口的IP地址指定为静态RP地址
[LSW1]pim
[LSW1-pim]static-rp 1.1.1.1
[LSW2]pim
[LSW2-pim]static-rp 1.1.1.1
[LSW3]pim
[LSW3-pim]static-rp 1.1.1.1
[LSW4]pim
[LSW4-pim]static-rp 1.1.1.1
[LSW5]pim
[LSW5-pim]static-rp 1.1.1.1
5. 在LSW5上配置稳定优先组播负载分担
[LSW5]multicast load-splitting stable-preferred
6. 配置LSW5的主机侧接口以静态方式批量加入组播组: 225.1.1.1～225.1.1.3
[LSW5-Vlanif200]igmp static-group 225.1.1.1 inc-step-mask 32 number 3
7. 验证稳定优先组播负载分担的配置
8. 为LSW5的各上游接口配置不同的组播负载分担权值，实现组播不均衡负载分担
[LSW5-Vlanif40]multicast load-splitting weight 3
[LSW5-Vlanif50]multicast load-splitting weight 2
9. 配置LSW5的主机侧接口以静态方式批量加入新的组播组
[LSW5-Vlanif200]igmp static-group 225.1.1.4 inc-step-mask 32 number 3
10. 验证组播不均衡负载分担的配置
