In general, you can enter the exit command from one of the speci?¬?c con?¬?guration modes
to return to global con?¬?guration mode. Press Ctrl-Z to leave the con?¬?guration mode
completely and return the router to the privileged EXEC mode.
In terminal con?¬?guration mode, an incremental compiler is invoked. Each con?¬?guration
command entered is parsed as soon as the Enter key is pressed.

Configuring a Cisco Router 285
If there are no syntax errors, the command is executed and stored in the running
con?¬?guration, and it is effective immediately.
Commands that affect the entire router are called global commands. The hostname and
enable password commands are examples of global commands.
Commands that point to or indicate a process or interface that will be con?¬?gured are called
major commands. When entered, major commands cause the CLI to enter a speci?¬?c
con?¬?guration mode.
