Which of the following packets are OSPF packets? (Choose all that apply.)
OSPF (Open Shortest Path First) utilizes several types of packets for communication. The HELLO packet (A) is used for establishing and maintaining adjacency with other OSPF routers. The LSR (Link State Request) packet (B) is used by OSPF routers to request more recent Link-State Advertisements (LSAs) from peers. The LSU (Link State Update) packet (C) is used to send LSAs to other OSPF routers. However, the LSA itself (D) is not a specific packet type but rather the information content that is carried within the LSU packets.
A,B and C. LSA is not a specific packet type, which is carried via as an Information on LSU.

A. HELLO This packet is used to establish and maintain OSPF neighbor relationships by sending periodic hello messages. B. LSR (Link State Request) This packet is sent by a router to request Link State Updates (LSUs) from its neighbors. C. LSU (Link State Update) This packet contains the actual link-state information, such as LSAs (Link State Advertisements), used to update the OSPF routing tables. D. LSA (Link State Advertisement) This is not a packet type by itself but rather a type of information contained within LSUs. LSAs describe the state of the links and are the building blocks of the routing information in OSPF. Therefore, the OSPF packets from the given options are A, B, and C. The option D refers to the content of LSUs but is not a packet type on its own.
