PPP negotiation not finishing IPCP

[netone.cisco]

Hello everybody.

I have been doing some test using a 2811 router as an ADSL BRAS. Its my first contact with this technology. ADSL is OK because the modem/CPE starts authentication gets a response (after RADIUS accept which returns the IP) but it doesnt finish IPCP and the connection ends and restarts again.

Authentication is through PPPoE

I see that when the router starts IPCP negotiation the cpe makes an authentication request again (even though it was already accepted before)

Please help me attached you will find a debug (ppp negotiation, ppp authentication, radius authentication and radius accounting), the running config and the topology

Hello,

It seems to be some kind of bug on the router. It gets stuck whenever I put a service-policy with traffic shapping on the virtual-template or assign one via radius. I have to reload the router to get back to normal.

Anyone knows if its a bug or theres a reason for this to happen?
