OSPF

配置ospf使得pc1和pc2能互通

接口的基本配置

R1:
R1(config)#int f0/0
R1(config-if)#ip address 192.168.2.1 255.255.255.0
R1(config-if)#no shutdown
R1(config)#int s1/0
R1(config-if)#ip address 172.16.0.1 255.255.255.252
R1(config-if)#clock rate 64000
R1(config-if)#no shutdown
R2:
R2(config)#int s1/0
R2(config-if)#ip address 172.16.0.2 255.255.255.252

R2(config-if)#clock rate 64000
R2(config-if)#no shutdown

R3(config-if)#clock rate 64000
R3(config-if)#no shutdown
PC1:
PC1> ip 192.168.2.2 24 192.168.2.1
Checking for duplicate address...
PC1 : 192.168.2.2 255.255.255.0 gateway 192.168.2.1
