[c-nsp] vrf-lite over a layer3 link

You need to tunnel it :-)
GRE is one option, and there is some info about this in the Building MPLS Based Broadband Access VPNs book

Subject: [c-nsp] vrf-lite over a layer3 link

 Hi all
This is my first post to this list, so I guess I should say hello ;-)
We are considering an advanced network design which allows us to separate
several services or customers using vrf-lite. There are some local sites
which are connected by our own cabling. Nevertheless there are also some
remote sites which are connected over a provider which provides common
layer3 links. I understand that vrf-lite uses vlan's to separate the
customers between ce and pe, I have seen these in all the examples I already
read. As supposely no provider supports vlan's but rather layer 3 lines the
big question is: How to span a network using vrf-lite over a provider?

Thanks for any ideas.
