[LSW1-GigabitEthernet0/0/4]port trunk allow-pass vlan 11
[LSW1-Vlanif10]ip add 10.10.1.1 24
[LSW1-Vlanif11]ip add 10.1.1.1 24
[LSW2]vlan batch 20 21
[LSW2-GigabitEthernet0/0/1]port link-type hybrid
[LSW2-GigabitEthernet0/0/1]port hybrid untagged vlan 20

[LSW3-GigabitEthernet0/0/1]port hybrid pvid vlan 30
[LSW3-GigabitEthernet0/0/4]port link-type trunk
[LSW3-GigabitEthernet0/0/4]port trunk allow-pass vlan 31
[LSW3-Vlanif30]ip add 10.10.3.3 24
[LSW3-Vlanif31]ip add 10.1.3.3 24
[LSW4]vlan batch 11 21 31 40
[LSW4-GigabitEthernet0/0/1]port link-type trunk
[LSW4-GigabitEthernet0/0/1]port trunk allow-pass vlan 11
[LSW4-GigabitEthernet0/0/2]port link-type trunk
[LSW4-GigabitEthernet0/0/2]port trunk allow-pass vlan 21
[LSW4-GigabitEthernet0/0/3]port link-type trunk
[LSW4-GigabitEthernet0/0/3]port trunk allow-pass vlan 31
[LSW4-GigabitEthernet0/0/4]port link-type trunk
[LSW4-GigabitEthernet0/0/4]port trunk allow-pass vlan 40
[LSW4-Vlanif11]ip add 10.1.1.4 24
[LSW4-Vlanif21]ip add 10.1.2.4 24
[LSW4-Vlanif31]ip add 10.1.3.4 24
[LSW4-Vlanif40]ip add 10.1.4.4 24
2. 配置单播路由协议，实现网络层互通：单播路由正常是组播路由协议正常工作的基础
[LSW1]ospf 1
[LSW1-ospf-1]area 0
[LSW1-ospf-1-area-0.0.0.0]network 10.1.1.0 0.0.0.255
[LSW1-ospf-1-area-0.0.0.0]network 10.10.1.0 0.0.0.255
[LSW2]ospf 1
[LSW2-ospf-1]area 0
[LSW2-ospf-1-area-0.0.0.0]network 10.1.2.0 0.0.0.255
[LSW2-ospf-1-area-0.0.0.0]network 10.10.2.0 0.0.0.255
[LSW3]ospf 1
[LSW3-ospf-1]area 0
[LSW3-ospf-1-area-0.0.0.0]network 10.1.3.0 0.0.0.255
[LSW3-ospf-1-area-0.0.0.0]network 10.10.3.0 0.0.0.255
[LSW4]ospf 1
[LSW4-ospf-1]area 0
[LSW4-ospf-1-area-0.0.0.0]network 10.1.1.0 0.0.0.255
[LSW4-ospf-1-area-0.0.0.0]network 10.1.2.0 0.0.0.255
[LSW4-ospf-1-area-0.0.0.0]network 10.1.3.0 0.0.0.255
[LSW4-ospf-1-area-0.0.0.0]network 10.1.4.0 0.0.0.255
3. 使能IP组播路由功能，并在所有接口上使能PIM-SM功能
[LSW1]multicast routing-enable
[LSW1-Vlanif10]pim sm
[LSW1-Vlanif11]pim sm
[LSW2]multicast routing-enable
[LSW2-Vlanif20]pim sm
[LSW2-Vlanif21]pim sm
[LSW3]multicast routing-enable
[LSW3-Vlanif30]pim sm
[LSW3-Vlanif31]pim sm
[LSW4]multicast routing-enable
[LSW4-Vlanif11]pim sm
[LSW4-Vlanif21]pim sm
[LSW4-Vlanif31]pim sm
[LSW4-Vlanif40]pim sm
4. 配置静态RP
[LSW1]pim
[LSW1-pim]static-rp 10.1.4.4
[LSW2]pim
[LSW2-pim]static-rp 10.1.4.4
[LSW3]pim
[LSW3-pim]static-rp 10.1.4.4
[LSW4]pim
[LSW4-pim]static-rp 10.1.4.4
5. 在LSW1、LSW2、LSW3成员端接口上使能IGMP功能
[LSW1-Vlanif10]igmp enable
[LSW2-Vlanif20]igmp enable
[LSW3-Vlanif30]igmp enable
6. 配置LSW1的VLANIF10接口静态加入组播组225.1.1.1，使接口下的用户能长期稳定地接收发往组播225.1.1.1的数据
[LSW1-Vlanif10]igmp static-group 225.1.1.1
7. 验证配置
