it’s quite simple article….
when you accidentally put wrong command at Cisco CLI…it would be like this
and you start waiting….for your entire lifetime…..wkwkwkw
the solution is using no ip domain-lookup on global config mode
Router(config)#no ip domain-lookup
voila…if you enter mismatch/typo character again….the picture above will not show up
the end….^_^
