Hi all,
IMHO there is a fundamental difference in the network visibility assumptions
reflectetd in the LDP- and RSVP-TE-based signaling proposals:

*	The former assumes that the network visibility of the U-PE is
limited to its Next Hop S-PE (or possibly a small set of Next Hop S-PEs)
*	The latter assumes that U-PE may be fully aware of the entire set
(or a subset) of S-PEs the MS-PW is going to traverse.

The full/partial path awareness presumption may be valid in certain
circmumstances,but the limited visibility one seems to be a bare minimum for
MS-PW.
 
Regards,
                    Sasha
