Dynamic routing is a method used in computer networks to automatically adjust the paths that data packets take based on current network conditions. Unlike static routing, where routes are manually set and do not change, dynamic routing protocols like RIP and OSPF allow routers to communicate with each other. This enables them to share information about network traffic and topology, ensuring that data takes the most efficient route. This adaptability helps maintain network performance and reliability, especially in large or complex networks. If a link goes down or becomes congested, dynamic routing can quickly find alternative paths, minimizing disruptions and improving overall data flow.
