What step in OSPF is described by a router inserting best paths into the routing table?

When a router inserts the best paths into the routing table, it is typically the result of the OSPF process that involves determining the most optimal path to a destination. This process is conducted after OSPF has completed its initial stages, such as discovering neighbors, exchanging link-state information, and building a topology of the network.

Choosing the best route is the step where OSPF evaluates all the available routes to a destination based on various metrics, such as cost, to determine the most efficient path. Once the best route is identified, it is then added to the routing table, allowing the router to use this path for forwarding packets to the intended destination.

In OSPF, this involves utilizing the Shortest Path First (SPF) algorithm, also known as Dijkstra’s algorithm, to calculate the best path based on the accumulated link-state information. This ensures that routing decisions are made based on the most current and reliable data about the network’s topology.

The other processes mentioned, such as exchanging link-state advertisements, establishing neighbor adjacencies, and flooding link-state updates, are essential for OSPF to function but directly relate to the discovery and establishment of routing information rather than the selection of the best path for the routing table.
