Typically, traceroute will reveal the number of MPLS hops. The MPLS
labels in error ICMPs do not contain any kind of router identifier, so
pin pointing them will be difficult.

By creating a full mesh through the MPLS core it may possible to
statistically show a minimum number of routers needed to support the
measurements. But I have no idea how tricky that measurement and
analysis will be.
