ASR Router not reachable after deleting ISE Route

Dears,

Is there any way to access the router without losing the saved configuration? For troubleshooting, I mistakenly delete the route from ASR Router to ISE. I tried local user and console but both are not working. Is there any way to access the device without restart

- Not if needs that route , the 'saved configuration' equals to the last saved configuration when restarting.

So, I will lose the configuration which is not saved if I restart, right?

yes if you not save the config, you will be loosing the config, from the time you saved to now what ever you changed.

for better visibility, copy show run and show startup config and compare out of the box ( so you know what is changed?)

Yes, unless you can achieve console - access. Use a local-admin account in
the future too in case ISE is unavailable. M.

If you do not have access device, and reboot, it only get last known good saved config, what ever config configured not save will be lost.

Will I lose the configuration if I try to change the admin password by accessing the rmon?
