For service demux I see no issue as well For transport I see two major issues: - MPLS requires new signalling protocol ... DC fabric and hosts which do act as PEs should be as simple as possible, but not simpler hence introduction of LDP or worse RSVP-TE to signal the labels seems not helpful. - MPLS FECs can not be summarized. With IP we just need information how to reach subnet X ... with MPLS (even if one would provide the relaxed match) FECs are still /32s That's a lot of them in large data centers.
