Cisco 870 Series ADSL/ Pots config

rosabenson

Level 1

Hi everyone,

I have a Cisco 871 Adsl router (IOS C870-ADVSECURITYK9-M), Version 15.1(4)M6)

This will be connected to an adsl line for dialup to the ISP. I have used the configuration before, but for some reason I cannot get it to light up the PPP connection. Under the interface Virtual-PPP1 interface I used to have the command: pppoe-client dial-pool-number 1

But now it gives me an error when I want to configure it there.

config-if)#pppoe-client dial-pool-number 1
                            ^
% Invalid input detected at '^' marker.

Any advice will be greatly appreciated:

Hello Rosa,

For a totally basic PPPoE-over-ADSL, I do not believe that using a Virtual-PPP interface in your case is the correct approach; this is used with L2TP targeted sessions.

You should correctly be using the Dialer0 interface just the way it is configured now, and add the following lines to your interface ATM0.1:

interface ATM0.1 point-to-point
 pvc 8/35
  pppoe-client dial-pool-number 1

You should totally remove the Virtual-PPP1 interface; you should not be needing it.

Can you give this a try?

Best regards,
Peter
