Commands take effect right away.

If you are an experienced Cisco router user, you probably just groaned. However, I find that this concept escapes new users.
As you type commands into the configuration mode, they immediately take effect. For example, if we change the router’s name, we see that the very next line contains the new router name:
Router1#config terminal
Enter configuration commands, one per line. End with CNTL/Z. Router1(config)#hostname MyRouter
MyRouter(config)#^Z
MyRouter#
As you can see, we changed the router’s name to MyRouter, which was immediately processed. This concept applies to everything in the router’s configuration mode.
