Your Cisco IOS router just had its flash: file system formatted by a ‘bad actor’ and you are now sadly looking at the ROMMON prompt wondering how long it is going to take you to download the correct image from cisco.com, get it onto your TFTP server…and you better hope this was a production device!
If you would have enabled Cisco’s IOS Resilient Configuration feature, you could be back up and running in a matter of minutes!
In this inaugural video techtorial from Hut8, we take a deep dive look at IOS Resilient Configuration, how to configure and validate it, and discuss why you can’t afford NOT to enable this feature on all your IOS routers!
Enjoy!
