Error enabling PPPoE

[Marcio Souza]

Hi!

I'm trying to configure a Cisco 1841 router to use PPPoE with ADSL, but when I try to enable PPPoE on fa0/0 I get the following error:

Router(config)#int fa0/0

Router(config-if)#no ip address

Router(config-if)#pppoe enable

PPPoE create bba subblock failed

This is a new router never used and I'm doing the first configuration on it. I have done the dialer configuration, but I have stopped on the above error and I can't finish the configuration.

I need some help, because I googoled the above error and I have found nothing how to solve it.

Hi Paul,

I tryed to configure the router as you have suggested but the same error appear every time I try to enable pppoe in any of the FastEthernet Interfaces, as following:

Int fa0/0

descritption DSL Interface

no ip address

ppoe enable

PPPoE create bba subblock failed

Another issue is when I tryed to configure "

ppp chap sent-username

USERNAME

password

P@ssw0rd (this is the password that ISP gave it  to you"

In this case I got the following error:

Router(config)#int Dialer1

Router(config-if)#ip address negotiated

Router(config-if)#ip mtu 1492

Router(config-if)#encapsulation ppp

Router(config-if)#dialer pool 1

Router(config-if)#ppp chap sent-username XXXXXXXXXXX password XXXXXX

                            ^

% Invalid input detected at '^' marker.

No matter how I try to do this I get the same error.

Regards,

Marcio

Hi Paul,

I have copied default configuration from flash to startup-config and tryed again. Despite that, I got the same error again, but instead of stop doing the configuration I have continued.

At the end the connection has been estabilished and all the users inside the Lan network are now reaching external sites pages.
