The control plane (control component) maintains and controls the forwarding table by learning the network topology from the routing protocols such as OSPF, IS-IS and BGP. Control plane is responsible for building the MPLS IP routing control by updating the label bindings which are exchanged between the routers. So when a packet arrives at the router the forwarding decision is taken by the data plane (forwarding component) by consulting the forwarding table, which is maintained by control plane. The packets are then forwarded towards the appropriate node based on the forwarding decision.
