单播路由更新--CCNA

单播路由更新





环境效果：R1和R2之间可以已单播的形式进行RIP路由更新，但R3不与R1,R2进行路由更新。
R1的配置
Router(config)#do show ip inter brief
Interface IP-Address OK? Method Status Protocol
FastEthernet0/0 192.168.10.2 YES manual up up

FastEthernet1/0 192.168.20.1 YES manual up up

Loopback0 11.1.1.1 YES manual up up

Router(config)#router rip
Router(config-router)#network 192.168.10.0
Router(config-router)#network 192.168.20.0
Router(config-router)#network 11.0.0.0
Router(config-router)#passive-interface default

Router(config-router)#neighbor 192.168.10.1

R2的配置

Router(config)#router rip
Router(config-router)#network 192.168.10.0
Router(config-router)#network 192.168.30.0
Router(config-router)#network 22.0.0.0
Router(config-router)#passive-interface default

Router(config-router)#neighbor 192.168.10.2

R3的配置

Router(config)#router rip
Router(config-router)#network 192.168.20.0
Router(config-router)#network 192.168.30.0
Router(config-router)#network 33.0.0.0
Router(config-router)#passive-interface default

结果：R1和R2之间可以互相更新路由信息
R1的路由信息

Router(config)#do show ip route
R 33.0.0.0/8 [120/1] via 192.168.20.2, 00:00:22, FastEthernet1/0
[120/1] via 192.168.10.1, 00:00:12, FastEthernet0/0
C 192.168.10.0/24 is directly connected, FastEthernet0/0
R 22.0.0.0/8 [120/1] via 192.168.10.1, 00:00:12, FastEthernet0/0
C 192.168.20.0/24 is directly connected, FastEthernet1/0
11.0.0.0/24 is subnetted, 1 subnets
C 11.1.1.0 is directly connected, Loopback0

R2的路由信息

Router#show ip route
R 33.0.0.0/8 [120/1] via 192.168.30.2, 00:00:42, FastEthernet1/0C 192.168.

R3的路由信息
