What is a key characteristic of dynamic routing?

Dynamic routing is characterized by its ability to adjust automatically based on changes in network topology. This means that when there is a change in the network, such as a new router being added or a link going down, dynamic routing protocols can quickly recalculate the best paths for data to travel through the network. They do this by using algorithms and protocols such as RIP, OSPF, or EIGRP, which exchange information between routers to maintain up-to-date routing tables.

This adaptability is crucial for maintaining network reliability and efficiency, as it reduces the need for manual intervention and configuration adjustments each time the network topology changes. It allows for more resilient network designs where routing can adapt to failures or changes without significant downtime.

Other characteristics of dynamic routing, while relevant, such as security or bandwidth consumption, do not define its key feature, which is the automated re-evaluation of routes. This makes it distinct from static routing, which requires manual configuration and does not adapt to changes in the network automatically.
