 network 12.1.1.0 0.0.0.255 area 0

 network 13.1.1.0 0.0.0.255 area 0

 network 14.1.1.0 0.0.0.255 area 0

R2配置

interface Serial0/0

 ip address 25.1.1.2 255.255.255.0

interface Serial0/1

 ip address 12.1.1.2 255.255.255.0

router ospf 110

 router-id 2.2.2.2

 network 12.1.1.0 0.0.0.255 area 0

 default-information originate always

R3配置

 network 14.1.1.0 0.0.0.255 area 0

R5配置

interface Serial0/0

 ip address 25.1.1.5 255.255.255.0

R6配置

interface Serial0/0

 ip address 46.1.1.6 255.255.255.0

no ip routing

ip default-gateway 46.1.1.4

4、配置PIM Dense Mode

R1配置

ip multicast-routing 

interface Serial0/1

 ip pim dense-mode

interface Serial0/2

 ip pim dense-mode

interface FastEthernet1/0

 ip pim dense-mode

R2配置

ip multicast-routing 

interface Serial0/0

 ip pim dense-mode       

interface Serial0/1

 ip pim dense-mode

R3配置

ip multicast-routing 

interface FastEthernet1/0

 ip pim dense-mode

R4配置

ip multicast-routing 

interface Serial0/0

 ip pim dense-mode

interface Serial0/2

 ip pim dense-mode

R6配置

interface Serial0/0

 ip igmp join-group 224.1.1.1

5、测试

此时说明PING Dense Mode已配置成功

R1配置

interface FastEthernet1/0

 ip pim dr-priority 2
