Explanation

(FIB,QoS,PFI). RIB is part of control plane 1.4. SP high end product Cisco IOS XR Software is partitioned into three planes: Control: Distributes routing tasks and management of the routing information base (RIB) to participating RPs; different routing processes can be running on different physical units. Data: Maintains the forwarding information base (FIB) changes across the participating nodes, letting the router perform as a single forwarding entity.
