配置PIM auto-rp 環境：三臺路由器串口相連，其它的配置如圖所示
要求：1. R1,R2,R3配置ospf 并把所有接口加入到area 0
2.配置R1為rp，配置R2為映射代理，把R3加入239.3.3.3組
3.練習本課所有show命令
?
步驟一：在每個路由器上配置1個loopback 口，并 配置三臺路由器接口使其連通。 R1的配置
R1(config)# interface Loopback0
R1(config-if)# ip address 30.1.1.1 255.255.255.0
R1(config)# interface Serial0
R1(config-if)# ip address 10.1.1.1 255.255.255.0
R1(config-if)# clockrate 64000
R1(config-if)#no shutdown R2的配置
R2(config)#interface Loopback0
R2(config-if)# ip address 40.1.1.1 255.255.255.0
R2(config)#interface Serial0
R2(config-if)# ip address 20.1.1.1 255.255.255.0
R2(config-if)#clockrate 64000
R2(config-if)#no shutdown
R2(config)#interface Serial1
R2(config-if)# ip address 10.1.1.2 255.255.255.0
R2(config-if)#no shutdown R3的配置
R3(config)#interface Loopback0
R3(config-if)# ip address 50.1.1.1 255.255.255.0
R3(config)#interface Serial1
R3(config-if)# ip address 20.1.1.2 255.255.255.0
R3(config-if)#no shutdown
步驟二：配置ospf路由協議，使其連通 R1的配置
R1(config)#router ospf 1
R1(config-router)# network 10.1.1.0 0.0.0.255 area 0
R1(config-router)# network 30.1.1.0 0.0.0.255 area 0 R2的配置
R2(config)#router ospf 1
R2(config-router)#network 10.1.1.0 0.0.0.255 area 0
R2(config-router)# network 20.1.1.0 0.0.0.255 area 0
R2(config-router)# network 40.1.1.0 0.0.0.255 area 0 R3的配置
R3(config)#router ospf 1
R3(config-router)# network 20.1.1.0 0.0.0.255 area 0
R3(config-router)# network 50.1.1.0 0.0.0.255 area 0
步驟三：配置R1為rp，配置R2為映射代理，把R3加入239.3.3.3組 R1的配置
R1(config)#ip multicast-routing? à啟用多播協議
R1(config)# interface Loopback0
R1(config-if)# ip pim sparse-mode? à接口PIM模式為稀疏
R1(config)# interface Serial0
R1(config-if)# ip pim sparse-mode
R1(config)# ip pim send-rp-announce Loopback0 scope 5 à指定R1為RP R2的配置
R2(config)#ip multicast-routing
R2(config)# interface Loopback0
R2(config-if)# ip pim sparse-mode
R2(config)# interface Serial0
R2(config-if)# ip pim sparse-mode
R2(config)# interface Serial1
R2(config-if)# ip pim sparse-mode
R2(config)# ip pim send-rp-discovery Loopback0 scope 5? à將R2指定為映射代理 R3的配置
R3(config)#ip multicast-routing
R3(config)# interface Loopback0
R3(config-if)# ip pim sparse-mode
R3(config-if)# ip igmp join-group 239.3.3.3 à將此接口加入到組239.3.3.3
R3(config)# interface Serial1
R3(config-if)# ip pim sparse-mode?
步驟四：查看組播路由表 R1#sh ip mroute 239.3.3.3?
