A Specific Password Reset Example

Example 20-4 shows an example password recovery/reset process on a 2901 router. The example begins with router R1 powered on and the user connected at the console. 2901 routers have compact flash slots, as well as USB slots that support flash drives, so for this example, I removed the flash memory to make the router boot into ROMMON mode. R1 is powered-on to begin. Here are the steps in the example:

Step 1. Turn the router power switch off.

Step 2. Carefully remove compact flash from the router.

Step 3. Turn the router power switch on.

Step 4. Watch initialization messages, waiting for the ROMMON> prompt.

Step 5. Once the router is in ROMMON mode, with a ROMMON> prompt, carefully reinsert the compact flash.
