Final answer:
Dynamic routing is a process in which routers automatically exchange route information using routing protocols. It enables efficient network management and packet delivery.
Step-by-step explanation:
Dynamic routing is a process in which routers automatically exchange route information with each other using routing protocols. The routers constantly update and exchange information about network topology and reachability, allowing them to dynamically adjust their routing tables.
For example, let's say there are three routers connected in a network. Router A receives information about the network from Router B and Router C. If Router B fails, Router A will automatically receive an updated route from Router C, enabling it to continue forwarding packets through an alternate path.
Dynamic routing is a powerful and efficient way to automate network management and ensure efficient packet delivery.
