Help with PPPoE configuration

[Yadhu Tony]

Hello,

I want to connect my Cisco 1905 router to a DSL modem (modem in fully bridged mode) and configure PPPoE to get the IP parameters from ISP. Currently we are using a Linksys home router as the internet gateway. Below can see the screenshot of PPPoE configuartion in my Linksys router and this is working fine.

Now I want to replace it with 1905 router. I configured my router like below but it is not working, means I cannot connect with Internet. Please can someone guide me with this. What I am doing wrong here?

interface GigabitEthernet0/0

Take "debug ppp neg" and "debug ppp auth" with "term mon".

If no output, leave modem off for few hours to clear anypossuble MAC lock.

Hi Paolo,

Thank you for your reply.

I took the debug output. Please have a look at it.
