What type of routing information does OSPF advertise?

The correct answer highlights that OSPF (Open Shortest Path First) advertises prefixes configured on interfaces, as well as learned prefixes from other routers within the same OSPF area. OSPF operates as a link-state routing protocol, which means it gathers information about the entire network topology and disseminates link-state advertisements (LSAs) that contain information about its routing paths. The prefixes advertised in these LSAs include both those assigned to the local router’s interfaces and those learned from neighboring routers through OSPF protocol exchanges.

By distributing this information, OSPF enables routers in the same OSPF area to construct a consistent and complete view of the network topology. This allows them to make informed routing decisions to efficiently direct traffic based on the most optimal paths available. Furthermore, the dynamic nature of OSPF allows for efficient convergence and adaptability to network changes, making it a suitable choice in diverse networking environments.

In contrast to the other options, which refer to static routing tables, MAC addresses, and routing priorities, OSPF specifically focuses on IP prefix learning and network topology, solidifying option B as the most accurate representation of the routing information OSPF advertises.
