实验拓扑：
通过直通线连接设备，手动先设置PC的IP地址。
路由器上的操作：
Router>en
Router#conf ter
Enter configuration commands, one per line. End with CNTL/Z.
1. 配置接口IP地址：
Router(config)#int fa0/0
Router(config-if)#ip address 172.16.0.1 255.255.0.0
Router(config-if)#no shut
%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up
Router(config-if)#end
2. 配置路由器密码：
Router#conf ter
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#line vty 0 4
Router(config-line)#password cisco
Router(config-line)#login
Router(config-line)#exit
Router(config)#enable password cisco
Router(config)#end
PC上的操作：
PC>ping 172.16.0.1
