第25章 PIM-DM配置

R1、R2、R3、R4配置Loopback地址，配置0SPF，Loopback地址与直连接口宣告到OSPF网络。

1.R1配置PIM-DM

[R1]interface GigabitEthernet 0/0/0
[R1-GigabitEthernet0/0/0]pim dm
[R1]interface GigabitEthernet 0/0/1
[R1-GigabitEthernet0/0/1]pim dm                         
[R1]interface GigabitEthernet 0/0/2
[R1-GigabitEthernet0/0/2]pim dm

2.R2配置PIM-DM

[R2]interface GigabitEthernet 0/0/0
[R2-GigabitEthernet0/0/0]pim dm
[R2]interface GigabitEthernet 0/0/1
[R2-GigabitEthernet0/0/1]pim dm

3.R3配置PIM-DM

[R3]multicast routing-enable 
[R3]interface GigabitEthernet 0/0/0
[R3-GigabitEthernet0/0/0]pim dm  
[R3]interface GigabitEthernet 0/0/1
[R3-GigabitEthernet0/0/1]pim dm

4.R4配置PIM-DM

[R4]interface GigabitEthernet 0/0/0
[R4-GigabitEthernet0/0/0]pim dm
[R4]interface GigabitEthernet 0/0/1
[R4-GigabitEthernet0/0/1]igmp enable 

5.R1查看PIM邻居

[R1]display pi neighbor 
 VPN-Instance: public net
 Total Number of Neighbors = 2
 Neighbor        Interface           Uptime   Expires  Dr-Priority  BFD-Session
 12.1.1.2        GE0/0/0             00:03:31 00:01:43 1            N          
 13.1.1.3        GE0/0/1             00:01:43 00:01:31 1            N       

6.PC1配置组播

7.组播服务器配置
