No, this is not possible unless you are creating an aggregate on a PE
somewhere (which would set the next-hop accordingly and allocate an
aggregate label to do the 2nd lookup). Why don't you just import the /24
into the Server vrf as well? you could use communities to tag them and
not advertise them beyond the PEs if you worry about it.
