hi,
Does anyone have a config for a Cisco 877 DSL router that is using PPOE?
I normally use PPOA and jsut can't can't this PPOE DSL line working.
For the ATM I am using this:
interface ATM0
no ip address
no ip mroute-cache
no atm ilmi-keepalive
pvc 8/35
encapsulation aal5snap
pppoe-client dial-pool-number 1
!
dsl operating-mode auto
Dor the Dialer:
interface Dialer1
ip address negotiated
ip access-group inbound in
encapsulation ppp
ip route-cache flow
dialer pool 1
dialer-group 1
no cdp enable
ppp authentication chap pap callin
ppp chap hostname eircom
ppp chap password 0 broadband1
ppp pap sent-username eircom password 0 broadband1
crypto map Crypto_Map
When I do a sh dsl int atm 0 it says showtime and the speed of the line and the CD light is constant.
I turned on debug ppp neg and debug ppp auth and see nothing!
Any ideas?

Thanks,
Should it matter I use and ATM 0 on my Cisco 877 as it looks like your use an ethernet port on an 878 or similar.
Also I've not been asked to add and IP to the dialer like you have below, although I do have a static IP:
ip address A.B.C.D 255.255.255.248
05-13-2009 05:14 AM
ATM Config
interface Dialer0
description Virtual Public Interface
ip address A.B.C.D 255.255.255.248
ip access-group outside_in in
ip mtu 1452
ip flow ingress
ip inspect STATEFUL_FW out
ip nat outside
ip virtual-reassembly
encapsulation ppp
dialer pool 1
dialer-group 1
no cdp enable
ppp authentication pap callin
ppp chap hostname USERNAME@static.sbcglobal.net
ppp chap password 0 SeCrEt
ppp pap sent-username USERNAMEl@static.sbcglobal.net password 0 SeCrEt
dialer-list 1 protocol ip permit

Thanks, I have never had to add the static Ip to the dialer one port before I leave it as "ip address negotiated" is it import to include this on the dialer0 interface if I'm using PPOE?

If you're using DHCP use 'ip address negotiated' instead.
05-13-2009 05:23 AM
Is this if our ISP is issing a dynmaic IP address?
05-13-2009 05:38 AM
If you have a static IP use-
ip address A.B.C.D 255.255.255.248
If you have a DHCP address use-
ip address negotiate
The rest of the config is the same.

Thanks,
Some of the example configs use:
vpdn enable
!
vpdn-group 1
request-dialin
protocol pppoe
and under the dialer
dialer remote-name redback
what are these?

It's another way to connect. With my provider it doesn't work, but it may with yours.
