PPPoe authentication failing for unknown reason.

Level 3

I'm trying to connect ADSL on SOHO 77 router. I'm using PPPoe client with CHAP authentication configuration. My login details are definitely correct. I recieve IP address from ISP's server but I get this message when I try to ping WAN addresses.

00:13:53: Vi1 PPP: Outbound cdp packet dropped, CDPCP state is Listen

I can ping my PC over Ethernet from console and PC can ping negotiated address from ISP over ethernet.

CDP is a Cisco discovery Protocol and the isp may not be running that. You can disable that under the interface using "no cdp enable"

So enter that command under the "interface virtual-template 1".

Also that CDP message shoudn't be a part of the problem.
