12.2 衔接RPF路由

1.R2配置OSPF

[R2]ospf 1 router-id 2.2.2.2
[R2-ospf-1]area 0
[R2-ospf-1-area-0.0.0.0]network 2.2.2.2 0.0.0.0 
[R2-ospf-1-area-0.0.0.0]network 10.1.1.0 0.0.0.255
[R2-ospf-1-area-0.0.0.0]network 23.1.1.0 0.255.255.255

2.R3配置OSPF

[R3]ospf 1 router-id 3.3.3.3
[R3-ospf-1]area 0
[R3-ospf-1-area-0.0.0.0]network 3.3.3.3 0.0.0.0 
[R3-ospf-1-area-0.0.0.0]network 23.1.1.0 0.255.255.255
[R3-ospf-1-area-0.0.0.0]network 192.168.3.0 0.0.0.255

3.R1配置pim

[R1]multicast routing-enable 
[R1]interface GigabitEthernet 0/0/0
[R1-GigabitEthernet0/0/0]pim dm
[R1]interface GigabitEthernet 0/0/1
[R1-GigabitEthernet0/0/1]pim dm 

4.R2配置pim

[R2]multicast routing-enable 
[R2]interface GigabitEthernet 0/0/0
[R2-GigabitEthernet0/0/0]pim dm
[R2]interface GigabitEthernet 0/0/1
[R2-GigabitEthernet0/0/1]pim dm       
[R2]interface GigabitEthernet 0/0/2
[R2-GigabitEthernet0/0/2]pim dm 

5.R3配置pim、igmp

[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]igmp  enable 

6.R2配置组播静态路由,指定到Source 2的RPF邻居为R1

[R2]ip rpf-route-static 10.1.2.1 24 12.1.1.1

7.R3配置组播静态路由,指定到Source 2的RPF邻居为R2

[R3]ip rpf-route-static 10.1.2.1 24 23.1.1.2

8.在R2和R3上分别显示到Source 2的RPF信息

[R2]display multicast rpf-info 10.1.2.1
 VPN-Instance: public net
 RPF information about source: 10.1.2.1
     RPF interface: GigabitEthernet0/0/0, RPF neighbor: 12.1.1.1
     Referenced route/mask: 10.1.2.0/24
     Referenced route type: mstatic
     Route selection rule: preference-preferred
     Load splitting rule: disable

[R3]display multicast rpf-info 10.1.2.1
 VPN-Instance: public net
 RPF information about source: 10.1.2.1
     RPF interface: GigabitEthernet0/0/0, RPF neighbor: 23.1.1.2
     Referenced route/mask: 10.1.2.0/24
     Referenced route type: mstatic
     Route selection rule: preference-preferred
     Load splitting rule: disable
