4配置举例

4.1组网需求

SwitchA、SwitchB和SwitchC组成一个PIM-SM的组播网络，其中SwitchA连接组播源，SwitchB和SwitchC连接不同的接收者，接收者指定源加入。

设备接口IP地址设备接口IP地址

SwitchAVlan-int10010.10.1.1/24SwitchCVlan-int10210.102.1.1/24

Vlan-int1210.12.1.1/24Vlan-int2310.23.1.3/24

Vlan-int1210.12.1.2/24

Vlan-int2310.23.1.2/24

4.2配置思路

SwitchA、SwitchB和SwitchC上分别配置单播路由协议，使各设备和组播源、接收者之间路由可达；

SwitchA、SwitchB和SwitchC上分别使能组播路由协议，并配置各接口的PIM-SM协议，连接接收者的接口配置IGMPv3协议；

配置SSM组地址范围。

4.3使用版本

本举例是在S12500-CMW520-B1131版本上进行配置和验证的。
