1921 ADSL over bridge modem

ITtelligent
Level 1
Level 1

Hello all,

I am having some trouble configuring an ADSL connection on a Cisco 1921. The DSL line is coming into a modem and I had setup the in bridge mode, and connected it to Ge0/1 on the 1921 configured a dialer interface with the ADSL details, default route to dialer interface, added the dialer group to ge0/1.

Not sure what step I'm missing. when I enabled various debugging for pppoe and ppp I don't even get any events showing it attempting to dial. I know my ADSL credentials and service are correct because I can set it up fine in the bridge modem.

Here is the config and version below.

Hi,

Can you setup on your Dialer interface chap authentication with these commands:

ppp chap hostname user@domain
ppp chap password 0 ADSLPASSWORD

If this still doesn't work please run the following debugs and paste the result into a text file:


debug ppp authentication
debug ppp negotiation
debug ppp packet
debug ppp error

Not every debug might be needed but to avoid doing back and forth it will be better to get all information in 1 shot .

Thanks

Hello,

you don't need any bridge commands, since none of your interfaces is in a bridge group. If you put your modem in bridge mode, your router effectively becomes the Internet edge device.

I have made some changes (marked in bold), implement those and see if you get your connection to work:
