Multi-VRF CE

Hi.

We have 290 sites over an MPLS cloud having IP reach-ability to each other.
The topology is as below:

different VRFs<--site1--PE1---"P routers" ---PE2---site2-->different VRFs

So the provider has established the connectivity between all sites.

As the topology, we have different networks on each site, and each network
requires isolated routing-table and connectivity to the same VRF on the
other sites.
Unfortunately the provider's policies doe not allow having sub-if to PEs
and having eBGP to PE and exchange our VRFs' labels and the routing table.
I mean that they just only provide the base connectivity to other sites
without any isolation between our local VRFs.
I should point that our topology is Hub'n'Spoke. So I imagined implementing
one tunnel from each site for each VRF to the hub. I know that this not an
efficient way.

So, what's your opinion?

Best Regards,
M. Moghaddas
