routing is enabled by default. To disable IP routing, enter the no ip routing command

and enter ip routing to re-enable it.

1.2 Getting Help

In any command mode, you can get a list of available commands by entering a question

mark (?).

Router>?

To obtain a list of command that begin with a particular character sequence, type in

those characters followed immediately by the question mark (?).

Router#co?

Configure connect copy

To list keywords or arguments, enter a question mark in place of a keyword or

argument. Include a space before the question mark.

Router#configure ?

memory Configure from NV memory

network Configure from a TFTP network host

terminal Configure from the terminal

You can also abbreviate commands and keywords by entering just enough characters to

make the command unique from other commands. For example, you can abbreviate the

show command to sh.

1.3 Configuration Files

Any time you make changes to the router configuration, you must save the changes to

memory because if you do not they will be lost if there is a system reload or power

outage. There are two types of configuration files: the running (current operating)

configuration and the startup configuration, which is loaded up in rebooting a router.

Use the following privileged mode commands to work with configuration files.

• configure terminal – modify the running configuration manually from the

terminal.

• show running-config – display the running configuration.

• show startup-config – display the startup configuration.

• copy running-config startup-config – copy the running configuration to the

startup configuration.

• copy startup-config running-config – copy the startup configuration to the

running configuration.

• erase startup-config – erase the startup-configuration in NVRAM.

• copy tftp running-config – load a configuration file stored on a Trivial File

Transfer Protocol (TFTP) server into the running configuration.

• copy running-config tftp – store the running configuration on a TFTP server.
