The subject of this question is OSPF Neighbor State. OSPF is a routing protocol used in computer networks, and it involves the formation of master-slave relationships and the exchange of link state information.
Step-by-step explanation:
The subject of this question is OSPF Neighbor State. OSPF stands for Open Shortest Path First and is a routing protocol used in computer networks. The process of forming master-slave relationships and exchanging link state information is part of the OSPF neighbor state.
After the Designated Router (DR) and Backup Designated Router (BDR) are elected, each router establishes a neighbor relationship with the DR and BDR. This process involves several states: Down, Init, 2-Way, Exstart, and Exchange.
