Which LSA packet carries master/slave relationship information?

• A. Hello packet
• B. DD packet
• C. LSA Update packet
• D. LSA Request packet

Answer: (B)

The correct choice indicates that the Database Description (DD) packet is responsible for carrying master/slave relationship information. In OSPF (Open Shortest Path First), the DD packet plays a crucial role during the initial stages of neighbor adjacency formation between routers. It is exchanged as part of the OSPF adjacency process and contains concise summaries of the data contained in the OSPF link-state database. This includes not only the router's own information but also indicates the master/slave relationship between the initiating router and its neighbor. During the OSPF process, the router that is in the master role will send DD packets to its peers, thus allowing the peers to understand the structure of the OSPF link-state database and manage the synchronization of routing information. The transmission of updated link-state information and acknowledgments also hinges on the clarity established through this master/slave dynamic. In contrast, the other packet types mentioned do not carry this specific master/slave information. Hello packets are used primarily for discovering and maintaining neighbor relationships, LSA Update packets are designed to transmit specific link-state advertisements, and LSA Request packets are utilized to request particular LSAs from neighbors, none of which encompass the overall master/slave relationship information fundamental to OSPF operation
