I'm not sure about MPLS limitations in the Sup2/MSFC2, but it wouldn't
surprise me if they're pretty major since those engines are much more
software driven and have substantially lower forwarding capabilities than
the Sup720/3BXL. The 3BXL does MPLS just fine, but I'm not running it in
a 'true' service provider environment. We run MPLS using LDP to
distribute labels to some non-Cisco gear and terminate Martini tunnels and
that seems to work pretty cleanly, although the hair-pinning needed to
land a Martini tunnel is somewhat strange...
