客户六台交换机 SWA 、 SWB 、 SWC 、 SWD 、 SWE 、 SWF 通过局域网连接在一起,组成 RRPP 环在 SWB 上査看 RRPP 状态如下:
<SWB>dis rrpp verbose domain 1
Domain ID : 1
Ring ID : 1
Ring Level: 0
Node Mode : Transit
Ring state:-
Enable Status : YesActive Status: Yes
Primary port: GigabitEthernet2/0/1 Port status: UP

如图所示组网中, RT1 、 RT2 和 RT3 之间运行 PIM SM 协议, RP 为 1.1.1.1RT3 上连有接收者,且在相应接口上使能 IGMP 在 RT3 査看单播路由表如下:
[RT3]display ip routing-table
Routing Tables: Public
Destinations : 10 Routes : 10
Destination/MaskProtoPreCost NextHop Interface
1.1.1.1/320SPF 10 1562 192.168.2.1 so/2/1
