The Label Distribution Protocol (LDP) is a protocol in the Multiprotocol Label Switching (MPLS) context that allows label switch routers (LSRs) to exchange label mapping information. It is a distributed protocol without a central controller. Instead, each LSR generates local label mappings for Forward Equivalence Classes (FECs) and propagates this information to adjacent LSRs which it maintains LDP sessions with.
