配置Cisco PIM Auto-RP
环境:三台路由器串口相连,其它的配置如图所示<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
要求:1. R1,R2,R3配置ospf 并把所有接口加入到area 0
2.配置R1为rp,配置R2为映射代理,把R3加入239.3.3.3组
3.练习本课所有show命令
步骤一:在每个路由器上配置1个loopback 口,并 配置三台路由器接口使其连通。
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 <?xml:namespace prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />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
步骤二:配置ospf路由协议,使其连通
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
步骤三:配置R1为rp,配置R2为映射代理,把R3加入239.3.3.3组
R1的配置
R1(config)#ip multicast-routing à启用多播协议
R1(config)# interface Loopback0
R1(config-if)# ip pim sparse-mode à接口PIM模式为稀疏
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为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将R2指定为映射代理
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将此接口加入到组239.3.3.3
R3(config)# interface Serial1
R3(config-if)# ip pim sparse-mode
步骤四:查看当前配置结果
