路由器的基本配置之telnet

路由器的基本配置

要通过telnet访问路由器，需要先通过console口对路由器进行基本配置，例如：IP地址、密码等。
实验拓扑图如图1所示。




图1、通过telnet访问路由器拓扑图

路由器的配置：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27

Router>enable ...................................进入路由器的特权模式 Router#configure terminal ................................进入路由器的全局配置模式 Enter configuration commands, one per line. End with CNTL/Z. Router(config)#interface f0/0 ...............................进入路由器的f0/0端口 Router(config-if)#ip address 192.168.1.1 255.255.255.0 ...配置路由器f0/0端口的Ip地址 Router(config-if)#no shutdown .......................启用f0/0端口 %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 ..............................退出配置模式 Router# %SYS-5-CONFIG_I: Configured from console by console Router#configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)#line vty 0 4 ...................进入路由器的VTY虚拟终端 Router(config-line)#password homechen Router(config-line)#login .....................以上两行配置VTY（即telent）的密码 Router(config-line)#exit Router(config)#enable password homechen ..............配置进入路由器特权模式的密码 Router(config)#end Router# %SYS-5-CONFIG_I: Configured from console by console Router#

在PC上测试是否可以和路由器连通：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

C:\>ipconfig IP Address......................: 192.168.1.100 Subnet Mask.....................: 255.255.255.0 Default Gateway.................: 0.0.0.0 C:\>>ping 192.168.1.1 Pinging 192.168.1.1 with 32 bytes of data: Reply from 192.168.1.1: bytes=32 time=21ms TTL=255 Reply from 192.168.1.1: bytes=32 time=8ms TTL=255 Reply from 192.168.1.1: bytes=32 time=8ms TTL=255 Reply from 192.168.1.1: bytes=32 time=8ms TTL=255 Ping statistics for 192.168.1.1: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 8ms, Maximum = 21ms, Average = 11ms

以上可以看出计算机和路由器能够连通了。

使用telent登录的路由器上

1 2 3 4 5 6 7 8 9 10 11 12 13

C:\>telnet 192.168.1.1 ..............远程登录到路由器上 Trying 192.168.1.1 ...Open User Access Verification Password: .........................输入telent密码 Router>enable Password: .........................输入进入特权模式的密码 Router#show interface f0/0 ........................查看路由器f0/0端口的信息（注意红色的up） FastEthernet0/0 is up, line protocol is up (connected) Hardware is Lance, address is 0001.96b9.6501 (bia 0001.96b9.6501) Internet address is 192.168.1.1/24
