Dynamic routing allows a router to do what without administrative intervention?

Dynamic routing enables routers to automatically learn and add the best routing information based on real-time network conditions. This process enhances the router's ability to adapt to changing network scenarios, such as varying traffic loads or hardware failures. By utilizing dynamic routing protocols (such as OSPF, RIPv2, or EIGRP), routers exchange information with one another, allowing them to update their routing tables without the need for manual configuration. This automatic adjustment ensures that data packets take the most efficient paths through the network, improving reliability and performance.

The concept of dynamic routing contrasts with static routing, where routes are manually configured, requiring administrative intervention for updates or changes. Dynamic routing facilitates scalability, making it particularly advantageous in large or complex networks.
