What Layer is MPLS on the OSI Seven-Layer Hierarchy?

MPLS (or Multi-Protocol Label Switching) is a network routing protocol that enhances network packet transmission by establishing pre-determined high-efficiency routes and optimizing data packet transfer through these high-efficiency routes. This network enhancement is achieved by assigning data packets an FEC or Forwarding Equivalence Class which determines how a data packet traverses a network. Often, the question arises, 'what layer is MPLS on the OSI Seven-layer Hierarchy?'

Since this protocol utilizes data-forwarding, which is often associated with Layer-2 of the OSI model or the 'Data Link' layer, users often assume MPLS must reside at the second layer of the OSI model. Alternatively, users often assume MPLS belongs to Layer-3 of the OSI model or the Network layer; however, counterintuitively, MPLS actually doesn't officially sit in either. MPLS sits in between these two distinct layers as the data-link attributes of MPLS can be decoupled from the forwarding mechanism MPLS is built on.
