Is the master/slave relationship of OSPF neighbors negotiated using DD packets?

The statement is true because in OSPF (Open Shortest Path First), the master/slave relationship between neighbors is indeed established through the use of Database Description (DD) packets during the OSPF adjacency formation process. When OSPF routers first attempt to communicate with one another, they exchange DD packets to summarize the contents of their link-state databases.

During this exchange, one router is designated as the master and the other as the slave. The master is the router that sends the DD packets, while the slave responds to them. This master/slave relationship determines which router has control over the communication sequence, which is essential for synchronizing the link-state databases between the routers, ensuring that both parties have a consistent view of the network topology.

The DD packets play a crucial role in establishing this relationship and in the overall efficiency of OSPF operations, as they encapsulate the initial state of each router's link-state information. This negotiation through DD packets is fundamental for achieving successful OSPF adjacencies.
