What type of routing allows routers to automatically adjust to changes in the network?

Dynamic routing is the type of routing that allows routers to automatically adjust to changes in the network. This adaptability is achieved through routing protocols that enable routers to communicate with each other, share routing information, and update their routing tables based on real-time network conditions.

Dynamic routing protocols, such as OSPF (Open Shortest Path First) and EIGRP (Enhanced Interior Gateway Routing Protocol), detect changes in the network topology, such as a failed link or the addition of new routers, and respond accordingly. This capability ensures that data packets follow the most efficient path to their destination, which is essential for maintaining network reliability and performance as conditions change.

In contrast, static routing requires manual configuration of routing tables, meaning any changes in the network must be addressed by manually updating those tables. Manual routing, similarly, suggests a hands-on approach with no automated adjustments, while policy-based routing focuses on traffic management based on predetermined policies rather than adapting to real-time changes.
