The Host workstations could be considered your CEs.  Are you trying use
a Layer2 VPN or a Layer3 VPN?

For a Layer3 VPN, import the Layer3 IP Subnet that the hosts are
connected to into the MP-BGP advertisement.  The Hosts would point their
default gateway to the VRF interface.

Layer2 VPNs are a little more complicated unless you want to look into
VPLS solution.

Sorry all, Oli pointed out that the ASCII diagram didn't do it any
justice.  I've attached a .gif of what I'm trying to do.  Basically, the
switches are not MPLS aware and I'm not looking to do EoMPLS, I'm just
looking to route traffic towards the router and shove it into a TE
tunnel.  Possible?

(for those of you who don't accept attachments, here's a link:

Thanks,
