Both LDP and RSVP *are* Label Distribution Protocols.  They both would be
responsible for assigning a label to a FEC and distributing it to their
neighbors.  If they are both running on the same LSR.  They could be
coming from either the same Label Space OR different Label Spaces.  The
answer to this like someone pointed out is "yes" and "yes".
