配置可控组播示例
组网需求
如图5-3所示，路由器连接的网络上有组播组G1(225.0.0.1)、G2（225.0.0.2）、G3（225.0.0.3）和G4（225.0.0.4）。现在控制VlAN10和VLAN20的用户只能观看G1和G2；VlAN30和VlAN40的用户可观看所有的组播组。
这里介绍IPv4网络中可控组播的配置示例。IPv6网络的配置示例和IPv4的配置示例类似，只需将配置IGMP Snooping换成配置MLD Snooping即可。
配置思路
在Switch上配置可控组播，可实现此需求。配置思路如下：
- 配置IGMP Snooping。
- 配置可控组播。
- 配置两个组播列表L1（G1, G2）和L2（G3，G4）。
- 配置两个模板P1和P2。
操作步骤
- 配置用户VLAN，并将接口加入用户VLAN。
