Hi,
As you configure the router, you will enter various sub-modes to set options, then return to the parent mode to display the results of your commands. You also return to the parent mode to enter other sub-modes. To return to the parent mode, you hit ctrl-z. This puts any commands you have just issued into affect, and returns you to parent mode.
Definately try out the following commands:
Router#show interfaces
Router#show ip protocols
Router#show ip route
Router#show ip arp
Thus you will configure a router.
Thanks...............................
