【CCNA640-802之189题最终完全解析】总结了很多网友的帖子，由于大多数网友只给了答案，现将题目给出，供大家参考：Topology Based LabLAB QUESTION:This topology contains 3 routers and 1 switch. Complete the topology.Drag the appropriate device icons to the labeled Device Drag the appropriate connections to the locations labeled Connections.Drag the appropriate IP addresses to the locations labeled IP address (Hint:use the given host addresses and Main router information)To remove a device or connection, drag it away from the topology.Use information gathered from the Main router to complete the configurationof any additional routers. No passwords are required to access the Mainrouter . The config terminal command has been disabled for the HQ router.The router does not require any configuration.Configure each additional router with the followingConfigure the interfaces with the correct IP address and enable the interfaces.Set the password to allow console access to consolepwSet the password to allow telnet access to telnetpwSet the password to allow privilege mode access to privpwNote: Because routes are not being added to the configurations, you will not be able to pingthrough the internetwork.All devices have cable autosensing capabilities disabled.All hosts are PCs=首先在main路由器上show run做为突破口interface FastEthernet0/0ip address 90 40!interface Serial0/0ip address 74 40clockrate 64000!ip classlessip http server!line con 0line aux 0line vty 0 4login!end根据show出来的F0/0,S0/0地址，计算IP地址范围,找出router1 f0/0,router2 s0/0 的地址然后根据图中hostA,hostC的IP地址，计算出地址范围，找出router1 f0/1,router2 f0/0 的地址具体如下：90/28 地址范围 76 - 91HostA的IP为：29/28 地址范围28 - 43那么Router1的Fa0/0口应该配上77。Router1的Fa0/1口应该配上4274/28 地址范围60 - 75HostB的IP为：25/28 地址范围24 - 39那么Router2的Serial0/0口应该配上61Router2的Fa0/0 口应该配上38=然后把正确的 线揽，设备，IP地址拖到相应的位置，正确后在router1,router2旁边会出现2个host,分别点击他们可以对router1,2进行配置。以右面的路由举例:RouterRouterenRouter#conf tRouter(config)#line console 0Router(config-line)#loginRouter(config-line)#password consolepwRouter(config-line)#exitRouter(config)#line vty 0 4Router(config-line)#loginRouter(config-line)#password telnetpwRouter(config-line)#exitRouter(config)#enable secret privpw(设置设置enable password或者enable secret都是可以的)通过在MAIN路由上SHOW RUN看到 已经在MAIN上配置了时钟,所以不需要咱们配clock rate Router(config)#interface s0/0Router(config-if)#ip address 61 40Router(config-if)#no shutRouter(config-if)exitRouter(config)#interface F0/0Router(config-if)#ip address 38 40Router(config-if)
