You could do this if you had a backbone router capable of supporting
VRFs and BGP4 address families - I've got this going in my lab, works
sort of ok if you don't need the backbone routers to ever actually talk
to each other, and instead function as two independent devices on either
side of the network. You could probably go so far as to leak routes out
of one VRF and into another VRF or the global address table if you
needed that kind of interconnectivity, but I haven't yet, so...
