chapter 9 ccna 2.Exam Points A quick way to remember whether IOS does a merge or an overwrite is to merge all copies to RAM and overwrite all other copy operations. Be sure to familiarize yourself with the commands listed in Table 16.2 and their functions.Hands-on Exercise 16.1Manipulating the Router's Configuration FileThe previous sections discussed the router's configuration files and how to manipulate them, and this exercise will help you deepen your knowledge of them. You will perform these steps on the 2600 router using the BosonNetSim simulator; see the Preface section of this book for a diagram of the network used by the simulator. After starting the simulator, click LabNavigator, double-click Exercise 16.1, and click the LoadLab button in that order. This will load the experimental exercise configuration from Chapters 10 and 15.Go to Router 2600-1. Click the tab Labs in the lower left corner of the window, then click the tab McGraw-Hill in the upper left corner (to the right of the tabs Standard and Custom). o Click the tab LabInstructions and select 2600-1 from the drop-down list Devices, or click the tab NetMap, then Double-click the device icon 2600-lo 2. Enter privileged EXEC mode on the router 2600-1 and view the operational configuration. To enter privileged EXEC mode: enabko Execute the command show running-configcSave the router's active configuration to NVRAM,and view the replication.Execute the command copy running-config startup-config; to view the copy: show startup-configChange the host name of the router to different,and then load the configuration saved in NVRAM into RAM. What is the hostname after restoring the configuration? Enter configuration mode (configure terminal) and use the command hostname different to change the name of the router to different. exit configuration mode: endo Use the command copy startup-config running-config to restore the configuration. The prompt will change to the previous name of the router (2600-1, the configuration recovery may take a few seconds to complete).5. deletethe configuration saved in NVRAM and view the configuration file in NVRAM.
