I have a 2621XM router and I need to config the it for PPPOE for my AT&T service. Will the config below work for me? I only have Fastethernet interfaces on this router. Also where do I type my username and password for the PPPOE login to the internet service.

Hi,
If you don't know the authentication protocol your ISP is expecting, configured both (PAP and CHAP)
Also you usually don't authenticate the ISP device so the config should looks like this:
interface Dialer 1
ppp authenticate pap chap callin
ppp pap sent-username cisco password cisco1
ppp chap hostname cisco
ppp chap password cisco1
Replace cisco/cisco1 by your login credentials received from your ISP
Troubleshooting links:
(just replace the ATM interface by your Fast interface)

Hope this helps
Thanks
Laurent.
