Resetting the password on a Cisco ASR1000 router is a crucial task for network administrators to maintain the security of their network infrastructure. Here's a step-by-step guide to help you with the process:

1. Connect to the console port of the Cisco ASR1000 router using a console cable and a terminal emulator program.
2. Power on the router and wait for the boot process to complete.
3. When the router prompts to enter ROMMON mode, press Ctrl + Break or Ctrl + Pause to interrupt the boot process.
4. In ROMMON mode, initialize the router by using the 'confreg' command to change the configuration register value to ignore the startup configuration.
5. Reset the password by reloading the router and entering privileged EXEC mode when prompted. You can then change the password using the 'enable secret' command.
6. Once the password has been changed, reset the configuration register value back to its original setting to boot from the startup configuration.
