According to this article, I can delete the current startup configuration files and return the router to its factory default settings with the erase nvram: and reload command.


R1#erase ?
  /all                       Erase all files(in NVRAM)
  /no-squeeze-reserve-space  Do not reserve space for squeeze operation
  flash:                     Filesystem to be erased
  nvram:                     Filesystem to be erased
  pram:                      Filesystem to be erased
  slot0:                     Filesystem to be erased
  startup-config             Erase contents of configuration memory

R1#erase nvram: ?

R1#erase nvram: 
Erasing the nvram filesystem will remove all configuration files! Continue? [confirm]
Erase of nvram: complete
*Mar  1 00:07:24.891: %SYS-7-NV_BLOCK_INIT: Initialized the geometry of nvram

I also tried erase startup-config and reload

The problem is nothing happens after that. It just stop responding right after reload command entered.

Proceed with reload? [confirm]

I did not get any prompt to proceed with reload as shown in the link above (or just refer to example below).


System configuration has been modified. Save? [yes/no]: no
Proceed with reload? [confirm]<enter>

    Are you connected to the serial console port at the default settings? (9600 8n1) It does take a minute for the system to POST. – Ricky Beam Apr 4 at 2:57
  • @RickyBeam, yes .. console, not physical bu virtual as this running on GNS3 – Sabrina Apr 4 at 3:12
