Most of those config errors are router configurations, it&#x27;s hard to disrupt that because it is tied to the hardware.  As a networking guy, I&#x27;m not surprised either.  Cisco&#x27;s interface is really awful and they have no interest in making it better.  They make tons of money selling expensive courses and certifications.  There is very little sanity checking in the interface which makes it easy to shoot yourself in the foot.
