In the OSPF link-state routing process, what describes the action of a router building a link-state database?

In the OSPF (Open Shortest Path First) link-state routing process, the action of a router building a link-state database is accurately described by building the topology table. The link-state database is a fundamental component of OSPF, as it contains information about the OSPF network's topology—specifically, the state of the links (or connections) between routers.

When a router operates in OSPF, it gathers information about its directly connected neighbors and their respective statuses, which includes metrics like the cost of links. This information is collected through the exchange of Link-State Advertisements (LSAs) among routers in the OSPF area. Each router updates its link-state database with this information to construct an accurate picture of the entire OSPF network topology.

The topology table, effectively another term for the link-state database, allows the router to make informed decisions about the most efficient paths for routing packets across the network. Once this database is populated with current link-state information, the router can execute the Shortest Path First (SPF) algorithm to calculate the best paths to each destination in the network.

As a result, building the link-state database is a crucial step that underpins OSPF's ability to perform efficient
