Which MPLS plane is responsible for packet forwarding?

A.
packet plane

B.
control plane

C.
routing plane

D.
forwarding plane

Explanation:
MPLS compliments IP technology. It is designed to leverage the intelligence associated with IP
Routing, and the Switching paradigm associated with Asynchronous Transfer Mode (ATM). MPLS
consists of a Control Plane and a Forwarding Plane. The Control Plane builds what is called a
“Forwarding Table,” while the Forwarding Plane forwards packets to the appropriate interface
(based on the Forwarding Table).
