At which layer of the OSI model is an MPLS label imposed?
MPLS (Multiprotocol Label Switching) labels are imposed between the data link layer (Layer 2) and the network layer (Layer 3) of the OSI model. This is known as the MPLS shim header, which allows for efficient and flexible data forwarding. Therefore, the MPLS label is imposed between Layer 2 and Layer 3.
The label is a shim header between L2 and L3
C is correct Layer 2.5
