Hi,
We have a 2811 router and we are to connect an ADSL service to its Fast Ethernet port using PPPoE. Carrier already supplied username and password but I'm having a hard time to make it work. I'm not sure if the PPPoE configuration of the carrier is already correct as they usually have issues with this but is there someone who can share a working config for a 2811 using Fast Ethernet for PPPoE?
If I configure PPPoE on the FE interface then I'm not getting any IP address and I'm not sure if I have done it right. But using IP address DHCP config, I'm just getting a regular private IP address from them.
I cannot find a really good document on how to make this work.
Thanks in advance.

Dear John,
Do a "debug ppp authentication" and "debug ppp negotataion" to find out any credential issue, but if you are getting an ip address means authentication is fine and connection is ok. also make sure you have default route to dialer interface,
find the below example config for ppp0e for fa interface
interface FastEthernet0/0
no ip address
duplex auto
speed auto
pppoe enable group global
pppoe-client dial-pool-number 1
no sh
!
interface Dialer1
bandwidth 100000
ip mtu 1492
ip address negotiated
encapsulation ppp
ip tcp adjust-mss 1452
dialer pool 1
ppp chap hostname xxx
ppp chap password yyy
ppp pap sent-username xxx password yyy
Thanks

Thanks. Here's my current configuration. I can only get an IP address if I do a "ip address dhcp" on Fa0/0 which is not the dialer interface. Still doesn't work. I would probably need to contact the carrier again.
interface FastEthernet0/0

Yes. Also you can directly connect the adsl line to a laptop/PC and create a dialup connection and check to confirm the line and credentials are fine.
Thanks

All configurations are correct. It was the carrier's fault. Thanks guys!
