Instructions
To configure the router (Gotha) click the console host icon that is connected ti a router ny a serial console cable.
You can click on the buttons below to view the different windows.
Each of the windows can be minimized by clicking the [-]. You can also reposition a window by dragging it by the title bar.
The "Tab" key and most commands that use the "CTRL" or "ESC" keys are not supported and are not necessary to complete this simulation. The help command does not display all commands of the help system.
Scenario
Central Florida Widgets recently installed a new router in their Gotha office. Complete the network installation by performing the inital router configurations and configureing RIPv2 router using the router command line interface (CLI) on the Gotha router.
Configure the router per the following requirements:
Name of the router is Gotha
Enable-secret password is mi222ke
The password to access user EXEC mode using console is G8tors1
The password to allow telnet access to the router is dun631ap
IPv4 addresses must be configured as follows:
Ethernet network 209.165.201.0/27 - router has fourth assignable host address in the subnet.
Serial network is 192.0.2.176/28 - router has last assignable host address in the subnet.
Interfaces should be enabled.
Router protocol is RIPv2.
Solution:
题目讲的很清楚,路由器配置界面里Ctrl和Esc的组合键不能用。另外help也没啥用。所以只能靠自己本事了。
不过这难不倒我们。
接下来就是在Gotha路由器上配置相关参数,要求的是主机名,Enable secret密码,console密码以及VTY密码。相信这些都不会有太大问题。可能会有变化,考试时请注意。
Router>enable
Router#configure terminal
Router(config)#hostname Gotha
Gotha(config)#enable secret mi222ke
Gotha(config)#line console 0
Gotha(config-line)#password G8tors1
Gotha(config-line)#login
Gotha(config-line)#line vty 0 4
Gotha(config-line)#password dun631ap
Gotha(config-line)#login
Gotha(config-line)#exit
可以使用show run验证一下配置,主要观察一下secret密码是否加密,确认一下你的配置,确保没有敲错!这个很重要,然后退出验证一下看看密码是否生效。
下面就是接口信息的配置,以太网接口使用了209.165.201.0/27 这个子网,路由器接口需要使用这个子网内第四个可分配的主机地址,千万不要配成209.165.201.3了,这个地址虽然是第四个,但是不是第四个可用的主机地址,正确的应该是209.165.201.4。
串行口使用了192.0.2.176/28这个子网,路由器接口需要使用这个子网内最后一个可分配的主机地址, 可用地址为192.0.2.177 - 192.0.2.190,所以路由器地址应该为192.0.2.190/28。这里一定注意,题目中没有提及谁是DTE谁是DCE,可以通过show controller看,比较简单的做法就是先配上,如果是DTE接口的话他会报错。
最后,打开接口。
Gotha(config)#interface fastethernet 0/0
Gotha(config-if)#ip address 209.165.201.4 255.255.255.224
Gotha(config-if)#no shutdown
Gotha(config-if)#interface Serial 0/0/0
Gotha(config-if)#ip address 192.0.2.190 255.255.255.240
Gotha(config-if)#clock rate 64000
Gotha(config-if)#no shutdown
