In ASR901 can you tag MSTP BPDU's

Question

I have an ASR901 ring, dual homed to 2 ME3800's with a management VPLS connection between the 3800's.  Running MPLS on all interfaces of the ring.  Would like to use a VRF for in-band management of the 901's.  These devices will be located at customer premises.  I am using SVI's for MPLS interfaces and SVI's for in-band Management interfaces on the ring.  Untagged encaps for MPLS and Tagged (vlan 2) for Management.   In the 3800's, I have a VPLS to bring the traffic back to the Management router.  So basically, in-band management uses a Layer 2 vlan switching on the ring, with vlan interfaces attached to a VRF.  Customer traffic uses MPLS cross-connects.
Problem is the need for MSTP so management can be dual homed to both 3800's and Layer 2 Protocol forwarding over the VPLS in order for STP to work properly.
This doesn't work because the management traffic is tagged VLAN 2 and the BPDU's are untagged, therefore they are getting dropped at the service instance ingress to the 3800's (encap dot1q 2).  Is there a way to tag MTSP BPDU's to make this work?  MSTP is the only STP option on the ASR901.
Or is there a way to add a management interface to an EFP cross-connect?  Or some other way to dual home the in-band management while using a VRF for management?  Note ASR901 doesn't support VPLS.

Thanks for the link but unfortunately it didn't help.  Although I did follow the instructions on the link but without success, I noticed that the link spoke of the iPod nano (5th generation).   I'm wondering if the tagging feature isn't available for the iphone 4s.  I bet it is but something just isnt right.
