Yes, a few production IP networks use MPLS on Label Switching
Routers now.
Probably 90% of our backbone traffic traverses an MPLS LSP.
As a matter of operational concern, we do not display Layer 3
IP hops within the MPLS LSP. Therefore troubleshooting from
an external perspective may be more difficult -- feel free to
involve our NOC.
LSRs with MPLS are in use in at least 3 networks today.
1 has an almost complete deployment, 1 has a regional deployment,
and 1 uses them as 'one-offs' for traffic engineering.
(as another potentially confusing detail, 'standard IP routers' are
'retrofitted' with MPLS, such that the same box becomes a hybrid
IP and MPLS router/switch)
