Cisco PPPoE Server Configuration Example

Hi Kevin,

I’d start with a couple of debug commands:

  • debug ppp
  • debug dialer
  • debug pppoe

That should show something when it’s flapping. About VPDN, I just checked but I don’t think you can do this for PPPoE on the client. Here’s what I have on IOS 15:

Client(config)#vpdn enable 

Client(config)#vpdn-group MY_GROUP
Client(config-vpdn)#request-dialout
Client(config-vpdn-req-out)#protocol ?
  l2tp  Use L2TP

I looked around to see if there is anything for IOS 12.4 but I don’t think so. On the ASA, it seems to be possible:
