Description (partial)

We have dual stack IP on the dialer.
If the router boots up, the IPv6 address is assigned to the dialer.
If we do a clear PPP, the IPv6 address is not coming back.
We have to shut / no shut the Dialer in order to make it work again.

We only have this issue when the PE is an ASR9K, when it is a 7200 it is working fine.
Also, the same configuration works fine on 153-3.M2, even with ASR9k.
Issue specific to  153-3.M3.
