Configuring the ADSL Interface
Note
Step 3
When the System Configuration dialog asks whether you want to view the current interface summary,
press Return or enter yes.
Step 4
If you have not configured the router before, or if you want to change the configuration, you should
now configure global parameters, passwords, network management, and routing protocols. Refer to the
procedures in the IOS configuration guides and command references. Press Return to accept the
default values.
The System Configuration dialog prompts you to configure network interfaces. When you reach the
Step 5
ATM interface, determine which protocols you want on the interface, and enter the appropriate
responses. (You must have previously enabled these protocols as part of the global configuration.)
Step 6
If your router has more than one LAN interface, repeat
The configuration you entered is displayed as a command script, and you are asked if you want to use
Step 7
it. If you enter no, the information you just entered is discarded, and you can begin the configuration
again. If you enter yes, the configuration is saved in the startup configuration:
Use this configuration? [yes/no]: yes
Building configuration...
Use the enabled mode 'configure' command to modify this configuration.
Press RETURN to get started!
The configuration is saved. If you added an interface, the router reboots in the new configuration when
you press Return.
You can configure the router for ATM and ADSL parameters using the following scenarios:
•
•
•
•
•
The scenario configurations above are identical to those for the Cisco 827-4V router. To configure these
scenarios on the Cisco 1720, 1721, 1751, and 1760 routers with the ADSL WIC, refer to the Cisco 827
Routers Software Configuration Guide.
