When designing enterprise routing, network architects should first figure out whether they should use static or dynamic routing. Static routing implies manually defining routes on devices and dynamic routing implies using a dedicated routing protocol that will build the routing table. The dynamic routing protocols most often used in modern networks are EIGRP, OSPF, and BGP.
Large networks, including the Internet, are based on the Autonomous System (AS) concept. An AS defines a group of network devices under a common administration and most often this defines a large organization or an ISP. Routing protocols can be classified based on different . . .
