Routing table and FIB table

The functions and meanings of the routing table and FIB table are as follows:
Routers forward packets based on routing tables and forwarding information base (FIB) tables. Each router maintains at least one routing table and one FIB table.
A routing table stores routes discovered by various routing protocols. Routes are classified into the following types based on the origin:
-Direct route: is discovered by link layer protocols.
-Static route: is manually configured by network administrators.
-Dynamic route: is discovered by dynamic routing protocols.
Each entry in the FIB table contains the physical or logical interface through which a packet is sent to a network segment or host to reach the next router. An entry also indicates whether the packet can be sent to a destination host in a directly connected network.
