How to erase router configurations

This article assumes that you are already connected to the router and have access to the EXEC mode CLI (i.e. the prompt ends with a # sign, similar to Router#. If you can't get to this prompt because of an unknown password, check out this knowledgebase article.

To erase your router configurations, follow these steps:

  1. From the privileged EXEC prompt, type the command erase startup-config which will delete the startup configuration.
  2. When you receive the following message:

    Erasing the nvram filesystem will remove all configuration files! Continue? [confirm]

    Press ENTER to confirm.
  3. Now restart the router by entering the command reload.
  4. You may receive a message that says:

    System configuration has been modified. Save? [yes/no]:

    Type no and press enter to ensure you don't save anything before reloading.
  5. Finally, you will receive the following message:

    Proceed with reload? [confirm]

    Press ENTER to confirm.

When the router restarts, it should prompt you to enter the initial configuration dialog, at which point you can disconnect from the router.
