[c-nsp] VPDN Problem

[Arie Vayner (avayner)]

Yes, it is sent from the LAC.
This is a message from the RFC, but I would assume it has something to do with the PPP/L2TP negotiation between the LAC and LNS, and the LAC not agreeing to something sent from the LNS...

The debugs below should help.

Hi Arie,

I mean, that if you've got a DSL-line with 160kbit upstream and you use 
it all.

The main thing I don't understand, is the error message "invalid 
destination". Do I understand it right, that the message I see in sh 
vpdn hist fail is send by the LAC to our LNS?

Sebastian
