Hello!
You know, while studying I came across this certain command which is "no cdp run". I know what it does, but why do they have this command? What kind of situation would you want no cdp to be ran?

I work for an msp and I see it all the time with isp edge routers. Its a pain in the ass from our point of view, but literally every device I see has cdp turned off

Its generally turned off for security reasons. If an outside attacker can see the iOS version you are running then you are more susceptible to them taking advantages of any bugs that may be present

Well run is for global and enable is for an interface.
I could see turning it off if you have a mixed environment and the devices on the other ends are not Cisco.
