How to Configure Cisco Routers for DSL

When you purchase a C2811-VSEC/K9 router for networking your computers, setting up the equipment is the easy part. Once you have your Cisco router installed, you must then configure the router to work with your DSL service. While many routers can be configured over the Internet, configuring a Cisco router requires a special program that makes it possible for the router and the computer to communicate with the DSL network.

Instructions
1. Download and install HyperTerminal to your computer. HyperTerminal was included in Windows systems up until Windows Vista, but now you must install HyperTerminal to your system to install a Cisco router for DSL. HyperTerminal can be downloaded from the website of the manufacturer, Hilgraeve (see Resources).

2. Launch HyperTerminal on the computer. To launch, go to "Start > All Programs," click the "HyperTerminal" folder and then click the program name. When HyperTerminal opens, type a name for the session, click "OK" and then go to "File > Properties." In the "Connect Using" section,C2821-VSEC-SRST/K9 click on the computer port where you plugged in the Cisco router.

3. Press the "Configure" button. Enter "9600" into the "Bits per second" field, "8" in "Data bits," "None" in "Parity," "1" in "Stop bits" and "None" in "Flow Control." Click "OK."

4. Go to the "Call" menu and choose "Disconnect." Then, return to the "Call" menu and click "Call." Keep pressing the "Enter" key until a prompt appear in the HyperTerminal screen.
5. Type the following commands at the prompt, one at a time: "Router#configure terminal," "Router(config)#service timestamps debug datetimemsec," "Router(config)#service timestamps log datetimemsec," and "Router (config)#end." Between each command, press "Enter" to bring up a new command line. This configures the timestamp.

6. Turn off the logging console during the configuration process. To turn off the console, type "Router#configure terminal" and then press "Enter," type "Router(config)#no logging console," press "Enter" again," and then type "Router(config)#end" and press "Enter."

7. Enter the following prompts, which create flexibility in configuration options, according to the Cisco website: "Router#configure terminal," "Router(config)#ip routing," "Router(config)#ip subnet-zero," "Router(config)#ip classless" and "Router(config)#end."

8. Send the commands to configure the point-to-point protocol parameters for the C2851-35UC-VSEC/K9 router: "Router#configure terminal," "Router(config)#vpdn enable," "Router(config)#no vpdn logging,"
"Router(config)#vpdn-group pppoe,"
"Router(config-vpdn)#request-dialin,"
"Router(config-vpdn-req-in)#protocol pppoe" and "Router(config-vpdn-req-in)#end."

9. Create an IP address on the Cisco DSL network by entering the following command into HyperTerminal: "Router(config-if)#ip address ." Configure the virtual circuit, according to the Cisco page, with the following commands: "Router#configure terminal," "Router(config)#interface atm 0," "Router(config-if)#pvc," "Router(config-if-atm-vc)#pppoe-client dial-pool-number 1," "Router(config-if-atm-vc)#no shut," "Router(config-if-atm-vc)#end."

10. Set up the Dialer connections with a static IP address for the router. To setup the connections,
enter the following commands: "Router(config-if)#ipnat outside,"
"Router(config-if)#encapsulation ppp," "Router(config-if)#dialer pool 1," "Router(config-if)#ppp chap hostname ," "Router(config-if)#ppp chap password ,"
"Router(config-if)#ppp pap sent-username password ," "Router(config-if)#end, "Router#configure terminal, "Router(config)#ip route 0.0.0.0 0.0.0.0 dialer1" and "Router(config)#end."

11. Turn the logging console back on and save the changes that you made. To turn on the console and save changes, enter the commands "Router#configure terminal," "Router(config)#logging console," "Router(config)#end," "Router#write memory."

Tips & Warnings
• Information in should be replaced with the data listed inside. For instance, in a command should be replaced with the VPI or VCI number, and should be replaced with your IP address. The Cisco 2811 router website provides a form detailing the information that you must know about your DSL connection before configuring your website. Some of the information, you should already know. Some of the information must be obtained the service provider.
