路由器RIP及OSPF配置
Rip配置:
基本网络配置如上图
Router0配置:
Router0(config)#router rip
Router0(config-router)#network 192.168.1.0
Router0(config-router)#network 192.168.2.0
Router0(config-router)#network 192.168.3.0
Router0(config-router)#network 192.168.4.0Router1配置
Router1(config)#router rip
Router1(config-router)#network 192.168.1.0
Router1(config-router)#network 192.168.5.0Router0:

C 192.168.3.0/24 is directly connected, Loopback1
C 192.168.4.0/24 is directly connected, Loopback2

R 192.168.4.0/24 [120/1] via 192.168.1.1, 00:00:16, FastEthernet0/0
C 192.168.5.0/24 is directly connected, Loopback0C代表直连,R代表用RIP协议学习到的路由信息
OSPF协议配置
OSPF协议有域的概念,只有相同域中的路由才交换链路信息,不同域间除了与0域(主干区域),与其他域不交换路由信息,所以如果要让所有域连通,每一个非主干域都要直接与主干域相连接;
Router0 配置:
Router0(config)#router ospf 1
Router0(config-router)#network 10.1.1.0 0.0.0.255 area 10
Router0(config-router)#network 10.1.2.0 0.0.0.255 area 10
Router0(config-router)#network 192.168.1.0 0.0.0.255 area 10Router1(config)#router ospf 1
Router0(config-router)#network 192.168.1.0 0.0.0.255 area 10
Router0(config-router)#network 192.168.2.0 0.0.0.255 area 0Router3配置:
Router1(config)#router ospf 1
Router0(config-router)#network 192.168.2.0 0.0.0.255 area 0
Router0(config-router)#network 10.2.1.0 0.0.0.255 area 1配置完成以后,测试各个路由都可以ping通再查看各路由的路由表
