The Label Distribution Protocol (LDP) [RFC5036] allows label advertisement mode negotiation at the time of session establishment. The LDP specification also dictates that only a single label advertisement mode be negotiated, agreed upon, and used for a given LDP session between two Label Switching Routers (LSRs).

Label Advertisement Discipline for LDP Forwarding Equivalence Classes (FECs)
The label advertising behavior of an LDP speaker for a given Forwarding Equivalence Class (FEC) is governed by the FEC type and not necessarily by the LDP session's negotiated label advertisement mode. This document updates RFC 5036 to make that fact clear. It also updates RFCs 3212, 4447, 5918, 6388, and 7140 by specifying the label advertisement mode for all currently defined LDP FEC types.
