When two routers exchange LSDB information, what forms first?

When two routers exchange Link State Database (LSDB) information, the primary relationship that is established first is a master/slave relationship. This relationship is crucial in the context of routing protocols like OSPF (Open Shortest Path First) and IS-IS (Intermediate System to Intermediate System), where one router is designated as the master, providing authoritative updates about the network topology, while the other acts as the slave, receiving and processing these updates.

The establishment of this master/slave relationship allows the routers to synchronize their LSDBs efficiently. The master router controls the exchange process, ensuring that the information is passed systematically and reducing the potential for conflict or confusion in the routing information being shared.

In contrast, while neighbor relationships and bidirectional relationships are important in routing protocols, they typically rely on the foundation laid by the master/slave relationship when it comes to LSDB synchronization. Workload distribution is also not a direct focus in the initial exchange, as the priority is on ensuring correct and consistent routing information is received.
