Routing Information Base (RIB): A data table stored in a router or a networked computer that lists the routes to particular network destinations. The RIB contains information about the topology of the network immediately around the router, including the cost (such as path length) associated with reaching each network destination. A router uses this information to determine the best path for forwarding packets. The RIB is built using information from routing protocols (like BGP, OSPF, etc.), and it may contain multiple potential paths to a destination. Routing decisions are made by a router by consulting the RIB and selecting the optimal route from the available entries based on the routing algorithm it uses.
