The MPLS architecture consists of the control plane and forwarding plane, each of which contains multiple protocols and entries. Which of the following tables is used to forward MPLS labeled packets?
MPLS packet forwarding is based on label information stored in the LFIB (Label Forwarding Information Base).
The role of different tables in MPLS:✅ RIB (Routing Information Base): Stores routing information, but does not handle MPLS label forwarding.✅ LIB (Label Information Base): Stores label bindings but is used for control-plane operations.✅ FIB (Forwarding Information Base): Used for IP forwarding, not MPLS forwarding.✅ LFIB (Label Forwarding Information Base): The correct table, which maps incoming labels to outgoing labels (or actions like swap, push, pop) and is used for actual MPLS packet forwarding.
