Which conceptual table created by routing protocols is used when processing an IP packet?
The conceptual table created by routing protocols that is used when processing an IP packet is the forwarding information base (FIB). The FIB is a table that contains the best routes to reach each destination network prefix, along with the outgoing interface and the next-hop address for each route. The FIB is derived from the routing information base (RIB), which is a table that contains all the routes learned from different routing protocols and sources.The FIB is used by the router to make fast forwarding decisions for each incoming packet, based on its destination address12.
