Software Configuration 5-5
Configuring the Router
Step 4 Enter the command config terminal at the enable prompt to enter configuration
mode:
Router# config terminal
You can now enter any changes to the configuration that you want to make. Press
Ctrl-Z to exit configuration mode.
To see the currently operating configuration, enter the command show running-config at
the enable prompt:
Router# show running-config
To see the configuration in nonvolatile random-access memory (NVRAM), enter the
command show config at the enable prompt.
Router# show config
To make your changes permanent, enter the command copy running-config
startup-config at the enable prompt:
Router# copy running-config startup-config
********
The results of the show running-config and show startup-config commands will differ if
you have made changes to the configuration but have not yet written them to NVRAM.
The router is now configured and will boot with the configuration you have entered.
Configuring the Router Using AutoInstall
The AutoInstall process is designed to configure the router automatically after connection
to your WAN. This process is useful when you must configure the router over serial 0.
In order for AutoInstall to work properly, a Transmission Control Protocol/Internet
Protocol (TCP/IP) host on your network must be preconfigured to provide the required
configuration files. The TCP/IP host may exist anywhere on the network as long as the
following conditions are maintained:
• The host must be on the remote side of the router’s synchronous serial connection to the
WAN.
