ccna 200 301 syllabus plural of fish.The configuration of direct, static, and default routes was described earlier. While interconnecting a network is possible through static routing, if the network is largeSuppose there are 100 routers, 101 networks, and two directly connected networks on each router, then the entries to be configured for static routes are100x(101-2)=9900 entries, which is almost impossible to achieve by hand. In addition, when the network changes, static routes do not reflect the topology changes well.This requires the use of dynamic routing protocols.5.5.1 Comparison of Static and Dynamic Routing**As described earlier, static routes are routing entries that are added manually by the administrator in the router. Unless the network administrator intervenes, static routeswill not change. Because static routes cannot react to changes in the network, a . It is generally used in networks that are small and have a fixed topology.The advantages of static routing are simplicity, efficiency, and reliability.Dynamic routing is the process by which routers in a network communicate with each other, pass routing information, and update router tables using the routing information received. It adapts to changes in the network structure in real time, and if a routing update message indicates that a network change has occurred, the routing software recalculates the route and sends out a new routing update message. These messages pass through the individual networks, causing each router to perform routing algorithms and update their respective routing tables to dynamically reflect network topology changes. Dynamic routing is suitable for networks that are large and have complex network topologies. Of course, various dynamic routing protocols will occupy network bandwidth and CPU resources to varying degrees.A comparison of static routing and dynamic routing is shown in Table 5.5.1.
