@mmarkwood - Your sample NetVanta configuration looks correct. The ADSL interface will cross-connect with the ATM interface and the ATM sub-interface will cross-connect with the PPP interface, as you have already configured.
The following guides provide more details on how to set up ADSL and PPPoE connections:
If you are experiencing issues bringing the connection up, it would be helpful to see the following:
1. Output to "show interface".
2. Output to "debug ppp verbose" as the PPP connection negotiates.
**Note: I would recommend logging the output of this debug
Please do not hesitate to let us know if you have any questions.
3. A copy of the configuration. Please remember to remove any information that may be sensitive to your network.
mmarkwood - I believe you opened a support ticket with Adtran Technical Support where it was determined that the PPPoE connection was unable to come up due to the mismatch PPP negotiation settings between the NetVanta and the Cisco router it was negotiating with.
The Cisco router was set to negotiate the PPP connection using CHAP. This means that the NetVanta would need to send a username and password through CHAP to the Cisco to authenticate the VPN connection. The NetVanta configuration settings based on your configuration above would need to look something like this:
interface ppp 1
ip address negotiated
ip access-policy all-selfprotect
ppp chap hostname dsluser
ppp chap password encrypted encrypteddslpass
cross-connect 3 atm 1.1 ppp 1 pppoe-client
Note that the ppp authentication chap command was removed from the configuration you provided. This command will actually require the Cisco to authenticate to the NetVanta, which will cause issues if the Cisco is not sending a CHAP username and password.
Are you having any additional issues with your setup? Please let us know if you have any further questions.
You are correct. I worked with support to determine the problem which wound up being that extra line in the config.
