如图所示:
用路由器模拟PC,R2模拟PC1,R3模拟PC2,R4模拟PC3。配置如下:
PC1:
R2#conf t
R2(config)#int f0/0
R2(config-if)#ip add
R2(config-if)#ip address 192.168.1.1 255.255.255.0
R2(config-if)#no sh
R2(config-if)#exit
R2(config)#ip default-gateway 192.168.1.254 (配置PC网关)
R2(config)#no ip routing
R2(config)#end
R2#
PC2:
R3#conf t
R3(config)#int f0/0
R3(config-if)#ip address 192.168.2.1 255.255.255.0
