Tip:
From the results, one can realize that the startup-config is the replica of
running-config. The startup-config file contents do not get erased when the
Router gets reloaded. However, manually we can erase the startup-config file.
Remove Startup-configuration or NVRAM by using the
following commands…
R1#
erase startup-config
You could also use the following commands to erase
the startup-config…
R1# write erase
OR
R1# wr er
Erasing the NVRAM file system will remove all
configuration files! Continue? [Confirm]
[OK]
