Answer options

• A. Router LSA
• B. Network LSA
• C. Summary LSA

Correct answer: A, B, C

Explanation

Router LSAs provide information about the routers within the area, Network LSAs describe multi-access networks, and Summary LSAs are used to summarize routes within the area. AS External LSAs, on the other hand, are used to advertise external routes and are flooded throughout the entire OSPF domain, not just a single area.
