Re: PPPOE CLIENT CONFIG Question

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

(just replace the ATM interface by your Fast interface)

Hope this helps

Thanks
