7组播典型配置

7.1        PIM-DM模式

【需求】

Multicast Source作为组播源，RECEIVER 1和RECEIVER 2是该组播组的两个接收成员。

【验证】

RouterA上的组播路由表：

[RouterA]disp multicast routing-table

Multicast Routing Table

Total 1 entry

(10.1.1.2, 226.1.1.1)

Uptime: 00:00:18, Timeout in 289 sec

Upstream interface: Ethernet2/0/0(10.1.1.1)

Downstream interface list: NULL

Matched 1 entry

 

【提示】

1、PIM协议是独立于特定的单播路由协议的，所以这里我们不关心单播路由协议，假定各个路由器之间相互可达。

2、c-bsr和c-rp推荐配置在同一台路由器上的loopback口上.

7.2        PIM-SM模式

【需求】

Multicast Source作为组播源，RECEIVER 1和RECEIVER 2是该组播组的两个接收成员。
