At the rommon2> prompt, enter reset, which will cause the router to reboot, but ignore the saved configuration file.Step 7 Press Ctrl-C to skip the initial configuration process. If the initial configuration process is not skipped, you will need to enter no0 after each configuration question This step is very important. If you use the configuration process to configure the router, you will lose your own backup configuration.Step 8 Put the router into privileged EXEC mode. Enter enable,at the Router> prompt to enter enable mode and you will see the Router# prompt.Step 9 Copy the startup configuration file to the running configuration file. Enter the copy startup-config running-config command to copy the file from NVRAM to memory. Note that you are not entering copy running-config startup-config,which will delete the startup configuration file.Step 10 Verify the configuration. Enter show running-config to view the configuration file. In this configuration file, since all interfaces are currently down, there are stMitdown commands under the interfaces. The administrator can now see the encrypted or unencrypted passwords (enable password, enable secret, vty, and console password), the unencrypted passwords can be reused, and the encrypted passwords need to be created with new passwords. To create a new password, you need toStep 11 Change the enablesecret password. Enter global configuration mode and enter the enablesecret command to change the enablesecret password.Step 12 Enable all interfaces. Execute the noshutdown command on each interface that will be used, and then execute the showipinterfacebrief command in privileged EXEC mode to make sure that the interfaces are configured correctly and that each interface that will be used should display "upup".Step 13 Use config-register configuration Register_setting to change the configuration registers. The configuration register value is set to the value in step 2 or 0x2102o For example: r1(config)# config-register 0x2102 Step 14 Save the modified configuration. Save the new running configuration to the startup configuration file with the copyrunning-configstartup-config command. This completes the password recovery. Enter the show version command to confirm that the router is using the configured configuration register values for the next boot.2.3.1.5 Disabling Password RecoveryIf someone can physically connect to the router, they can gain control of the device through the password recovery method. If the process is performed correctly, the router's configuration will not be corrupted. This attack is difficult to detect if the attacker does not make major changes. An attacker can use this attack method in order to discover the router's configuration and other relevant network information, such as traffic flow and access control restrictions.
