Which table contains LSAs from all routers in the same area?

Which table contains LSAs from all routers in the same area?

• A. Neighbors Table
• B. Topology Table
• C. Routing Table
• D. Link-State Database

Answer: (B)

In OSPF, all link-state advertisements from every router within an area are stored in the Link-State Database. This database holds the complete set of LSAs (Router LSAs, Network LSAs, Summary LSAs, etc.) for that area, giving each router the full picture of the area’s topology. The Topology Table, on the other hand, is built from the information in the LSDB and represents the network topology as used by the SPF algorithm to determine the best paths. So LSAs from all routers in the area live in the Link-State Database, while the Topology Table is a derived view used for route calculation.
