In this episode you will learn:
- The Routing Information Base (RIB) is the router's main routing table, operating on the control plane and containing all learned routes.
- The Forwarding Information Base (FIB) is a streamlined table derived from the RIB, used for high-speed packet forwarding on the data plane.
- Cisco Express Forwarding (CEF) is the mechanism that builds the FIB by selecting the best routes from the RIB.
- The `show ip route` command displays the RIB, while `show ip cef` is used to view the FIB, a key distinction for the exam.
- A common exam trap is confusing the roles and operational planes of the RIB (control plane) and the FIB (data plane).
