APPENDIX C
Erasing and Reloading the Router
For some of the CCNA 3 labs, it is necessary to start with a basic unconfigured router; otherwise, the configuration
parameters you enter might combine with previous ones and produce unpredictable results. The
instructions here allow you to prepare the router prior to performing the lab so that previous configuration
options do not interfere with your configurations.
The following is the procedure for clearing out previous configurations and starting with an unconfigured
router.
Step 1. Enter into privileged EXEC mode by typing enable.
Router>enable
If prompted for a password, enter class. (If that does not work, ask your instructor.)
Step 2. In privileged EXEC mode, enter the command erase startup-config.
Router#erase startup-config
The response from the router will be
Erasing the nvram filesystem will remove all files! Continue? [confirm]
Step 3. Press Enter to confirm.
The response will be
Erase of nvram: complete
Step 4. Now in privileged EXEC mode, enter the command reload.
Router#reload
response:
System configuration has been modified. Save? [yes/no]:
Step 5. Type n and then press Enter.
The router will respond with the following:
Proceed with reload? [confirm]
Step 6. Press Enter to confirm.
The first line of the response will be
Reload requested by console.
After the router reloads, the prompt will be
Would you like to enter the initial configuration dialog? [yes/no]:
Step 7. Type n and then press Enter.
The responding prompt will be
Press RETURN to get started!
Step 8. Press Enter.
Now, the router is ready for you to perform the assigned lab.
