Changing from PPPoA to PPPoE on Cisco 837

By john ·
I was recently informed by the new AT&T that they are changing my DSL service from PPPoA to PPPoE and I will need to make changes to all of my routers (we use Bellsouth's VPN Service over their DSL). I am not that familiar with configuring DSL Routers as I know enough to get me in trouble. My current ATM interfaces look like this:

interface ATM0
no ip address
atm ilmi-keepalive
pvc 0/16 ilmi
!
pvc 8/35
encapsulation aa15mux ppp dialer
dialer pool-member 1
!
bundle-enable
dsl operating-mode auto
!
interface Dialer0
ip address negotiated
encapsulation ppp
no ip route-cache
dialer pool 1
no cdp enable
ppp chap refuse
ppp eap refuse
ppp pap sent-username abc password 123

Can some one give me a template of what I need to changes to the interface to work with PPPoE?

PPPoE uses Bridging rather than routing to transport data

by Sumit_Singla In reply to Changing from PPPoA to PP ...

For PPPoA
=========

interface ATM0
no ip address
atm ilmi-keepalive
pvc 0/16 ilmi
!
pvc 8/35
encapsulation aa15mux ppp dialer
dialer pool-member 1
!

For PPPoE
=========

interface ATM0
no ip address
atm ilmi-keepalive
pvc 0/16 ilmi
!
pvc 8/35
protocol pppoe
pppoe-client dial-pool-number 1
!


I hope the above will help you change the config on your router from PPPoA to PPPoE.

Regards,

Sumit Singla
