Which type of LSA packet contains complete LSA information?

LS Update packets are crucial in the OSPF (Open Shortest Path First) protocol, as they contain the complete information about different types of Link State Advertisements (LSAs). When a router generates or receives these packets, they include the entire LSA content, which can encompass information such as network routes, associated metrics, and the state of the links. This complete LSA information allows routers to have a full understanding of the topology and route selections within an OSPF area, ensuring accurate and efficient routing.

In contrast, DD packets primarily serve as a means to negotiate the contents of LSAs and do not contain the complete LSA information. LS Request packets are utilized to solicit specific LSAs from neighbors, while LS Ack packets function to acknowledge the receipt of LS Update packets. None of these options provide the comprehensive LSA content like the LS Update packets do.
