Routing Fundamentals

Routing is the process of determining the best path for forwarding packets across a network.
The routing table contains mappings from network numbers to next hops.
The forwarding table is a data structure that stores the information needed to forward packets.
The forwarding table is used to make forwarding decisions.
The routing process builds the routing table.
The main difference between forwarding and routing is that forwarding refers to the process of moving packets between network interfaces, while routing refers to the process of determining the best path for forwarding packets.
