1、新建拓扑图。
2、ip规划：pc0:192.168.10.2/24pc1:192.168.20.2/24pc2:192.168.30.2/24router0 gig0/0:10.1.1.1/24router0 gig0/1:192.168.10.1/24router1 gig0/0:10.1.1.2/24router1 gig0/1:10.1.2.1/24router1 gig0/1:192.168.20.1/24router2 gig0/0:10.1.2.1/24router2 gig0/1:192.168.30.1/24
3、配置router0的接口：configure terminalinterface gigabitEthernet 0/1ip address 192.168.10.1 255.255.255.0no shutdownexitinterface gigabitEthernet 0/0ip address 10.1.1.1 255.255.255.0no shutdownexitdo show ip interface brief
4、配置router1的ip地址：configure terminalinterface gigabitEthernet 0/1ip address 10.1.2.1 255.255.255.0no shutdownexitinterface gigabitEthernet 0/0ip address 10.1.1.2 255.255.255.0no shutdownexitinterface gigabitEthernet 0/2ip address 192.168.20.1 255.255.255.0no shutdownexitdo show ip interface brief
5、配置router2的ip地址：configure terminalinterface gigabitEthernet 0/0ip address 10.1.2.2 255.255.255.0no shutdownexitinterface gigabitEthernet 0/1ip address 192.168.30.1 255.255.255.0no shutdownexit
6、配置个路由的ospf协议：router2的：router ospf 10network 192.168.30.1 0.0.0.0 area 10network 10.1.2.2 0.0.0.0 area 10exitexitshow running-configrouter1的:router ospf 10network 192.168.20.1 0.0.0.0 area 10network 10.1.2.1 0.0.0.0 area 10network 10.1.1.2 0.0.0.0 area 10exitexitshow running-configrouter0的：router ospf 10network 192.168.10.1 0.0.0.0 area 10network 10.1.1.1 0.0.0.0 area 10exitexitshow running-config
7、在pc0上进行验证：ping 192.168.20.2ping 192.168.30.2
