Is there a big difference between static and dynamic routing?

To be able to forward data packets, a router must be aware of the physical location of other routers and nodes on the Internet. Consequently, the router has a routing table, which is a database of network topology.

In simple routers, all routing information must be entered and maintained manually in the routing table. This is known as static routing.

More advanced routers support an automatic exchange of routing information with other routers. This exchange is called dynamic routing.
Dynamic routing is considered the most convenient kind of routing, as it allows routers to adjust spontaneously to changing network conditions.
The information exchange between routers is performed through the use of routing protocols. A routing protocol specifies how the routers should report changes and share information with each other and there exist several routing protocols, each with different characteristics and applications.
The routing protocols basically fall in two groups: There are Interior Gateway Protocols (IGP) that are used for routing information exchanges within autonomous networks (for example, a system of corporate local area networks), and there are Exterior Gateway Protocols (EGP) for exchanges between autonomous networks, that is, across the Internet. Of the first group, RIP (Routing Information Protocol) and OSPF (Open Shortest Path First) are the two most widely known and used protocols.
