You are correct, the traffic should be wrapped in IPv6CP which should be
carried over the PPP, not sure what kind of service you have from KPN but
I can't imagine there is one where they would interfere with this?

I can see the packet is sourced from your IID correctly, can you get a PPP
debug (I.e debug PPP packet) from the CPE?
