Subject: do we need to have disjoint label space for cr-ldp and rsvp-te

***: No you don't need to have disjoint label space for different label
distribution protocols, if you have a central entity responsible for
assigning different labels to different protocols. Otherwise you need to.
> 2:is there a specific reason for having interface specific label space for
> atm and frame relay ????
***:In the cassse of ATM and Frame realy we encapsulate label in L2 header,
e.g in the case of ATM we use VPI/VCI field of ATM header for label.
