What is a key role of a routing protocol?

The primary role of a routing protocol is to facilitate dynamic routing updates between routers in a network. This functionality is crucial because it enables routers to share information about network topology changes, allowing them to efficiently determine the best paths for data to travel through the network.

When a routing protocol is employed, routers automatically exchange routing information, adjusting their routing tables in real time to reflect any alterations in the network. This dynamic capability ensures that routing decisions can adapt to changes such as new devices being added to the network, link failures, or variations in network traffic patterns.

In contrast, managing user permissions, storing device configurations, and enforcing security policies are tasks associated with different layers of network management or security, which are not the primary functions of routing protocols. These responsibilities fall outside the scope of what routing protocols are designed to accomplish.
