VRFs is what you want.  Basically, using VRFs separates the router into
"logical sub-routers" - like VLANs do with switches on L2, but on L3.

MPLS *can* then be used to connect the same VRF on different routers
over "any transport in between", but it's not necessarily tied together.

(We've been using MPLS without VRF, for AToM, and VRFs without MPLS,
because the routers in question didn't do VRFs - so we used IP tunnels
to tie together the routers).
