Cisco 2611 DSL PPPoe connection configuration

Posted on 2008-11-02
Last Modified: 2013-12-14
We currently have a cable connection connected to one of our cisco 2611 routers. We are getting a new provider, and we need to configure the wan interface for dsl.

It's a PPPoe dialer with a dynamic ip. I have attached a snippet of our running config. If someone can provide me with the steps or configuration in order to switch over to the dsl while retaining the current config.

Current configuration : 2596 bytes

arshana can you elaborate please? I am not a complete newb when it comes to CLI but, i'm not exactly sure where to configure the username & password.
