4配置舉例

4.1組網需求

SwitchA、SwitchB和SwitchC組成一個PIM-SM的組播網絡，其中SwitchA連接組播源，SwitchB和SwitchC連接不同的接收者，接收者指定源加入。

設備接口IP地址設備接口IP地址

Vlan-int1210.12.1.2/24

Vlan-int2310.23.1.2/24

4.2配置思路

SwitchA、SwitchB和SwitchC上分別配置單播路由協議，使各設備和組播源、接收者之間路由可達；

SwitchA、SwitchB和SwitchC上分別使能組播路由協議，并配置各接口的PIM-SM協議，連接接收者的接口配置IGMPv3協議；

配置SSM組地址范圍。

4.3使用版本

本舉例是在S12500-CMW520-B1131版本上進行配置和驗證的。
