MPLS uses the CEF table adjacencies in establishing a Label Switched Path.
Additionally, each VPN Routing and Forwarding (VRF) uses a derived CEF
table, in addition to its own forwarding table.

There's a pretty good list 'mpls-ops' hosted at mplsrc.com if you want to
get more involved in MPLS.   Jim Guichard is an active participant on the
list so you can drill down about as deep as you want and get pretty good
answers.
