One of my colleagues went for the ICND 1 (640-822) exam and he failed to pass the exams with a small margin. He got few simulation questions, in which he was suppose the find out the IP address for the router interfaces connected in the topology provided. The show running command was disabled, he was suppose to use alternative IOS commands to determine the IP address assigned to the router interface.
In this scenario don’t panic, the best command to determine the IP address assigned to interface s in any router is “show ip interface brief” or Show ip interfaces. Here is the sample output of these commands
ITKE-DAC-3745R01#sho ip interface brief
