Did you previously do a password recovery pointing the config variable in rommon to “/harddisk:/no-config”? The router is trying to still load the config from harddisk:/no-config, we need to remove that rommon variable so that it will boot from the proper config file. Otherwise as you saw everytime you boot the router it will try a password recovery.

Hi,

to to enter to romain mode

also how to remove a no-config

sidshas03 · ‎03-13-2023

To enter ROMMON mode on the Cisco ASR9K Router, follow these steps:

Connect to the router's console port using a console cable and a terminal emulator program such as PuTTY.

Power on your router.

Interrupt the boot sequence by pressing the interrupt key (usually ctrl + interrupt) during the boot process.

You will see his ROMMON prompt like "rommon 1>".

To remove the "no-config" variable from ROMMON, you can do the following:

Enter the set command at the ROMMON prompt to display the current ROMMON variables. Look for the variable that sets the Alternate Configuration Source to "no-config". It will be as follows.
"BOOT_CONFIG=no configuration".

Enter the command "unset BOOT_CONFIG" to remove the "no-config" variable.

Enter the sync command to save your changes.

Enter the "boot" command to boot the router. Remove the "no-config" variable and the router should boot from the correct configuration file.
