Topic: Testing OpenWRT with Cisco ASR9000 BRAS (BNG)

Hi Guys!
I'm a systems engineer at Cisco Systems and now i'm testing IPv6 broadband solutions: Dualstack PPPoE + PrefixDelegation and IPoE Dualstack + PD with CPE under OpenWRT. Now I see neither Attitude Adjustment not Barrier Breaker don't do this out of box. I tried to setup IPv6 stack manually but didn't succeed too.
Cisco ASR9000 is a popular BNG platform worldwide (the newest one) and Cisco's IPv6 broadband designs are common practice in major SPs. Is anybody of you ready to validate and tune this case in a lab with me?
