This document presents the GMPLS Signaling mechanisms referred to as generalized label flagging method, and RSVP-TE/CR-LDP specific signaling extensions formats needed to ease forward-link label unavailability when the downstream label selection is restricted by the upstream node using the Label Set. It also relaxes backward-link label collision when the downstream label collides with competing label selection. This method introduces the Flagged Label Set object/TLV in order to prioritize the reservation of the labels included in the Label Set enabling to decrease the forward- and backward-link blocking probability.
