I had to downgrade a couple of Cisco 3925 routers last week and one of the steps in the instructions (link provided) was to change the boot command that was given by the following command:
Cisco-3925# show run | include boot
The downgrade went fine, but what I'd like to know is why this command didn't show any boot instruction before the downgrade was successful. Here is the output of that command:
How did the router boot before the downgrade in the first place?
