clearing current configuration of NCS-5501-SE

[from88]

Hello, have couple of NCS-5501-SE (version 7.5.2) routers. I would like to reset the current configuration.

What would be the most recommended way ? Do commit replace is still relevant for resetting the configuration ?
I've read that some people are doing ztp clean before commit replace. Is this mandatory ?

Thank you

Hi,

conf t

commit replace

these commands will wipe the configuration from xr; features such as bgp ospf etc configuration will be gone

it will not remove the admin config, which contains the local user/disaster recovery account, files on the disk etc

if you want to wipe the entire router; it would be best to do a usb boot;

you would download the usb boot file from the software page; extract the contents to the root of the usb and boot the router from the usb.

Hello @from88 , 

Reading out this topic, I'd just like to add the scenario on top of @tkarnani answer if you want to replace with another config file.

NCS5501SE#configure
NCS5501SE(config)#load <file url>
NCS5501SE(config)#show config   >>>> verify the loaded file
NCS5501SE(config)#commit replace

Hope it helps. 
Have a nice day. 
Kind Regards,
