Neighbor state:
z
Down: This is the initial state of a neighbor conversation.
z
Init: In this state, the router has seen a Hello packet from the
neighbor. However, the router has not established bidirectional
communication with the neighbor (the router itself did not
appear in the neighbor's hello packet).

communication with the neighbor (the router itself did not

z
Attempt: Available only in an NBMA network, Under this state,
the OSPF router has not received any information from a
neighbor for a period but can send Hello packets with a longer
interval to keep neighbor relationship.

z
Full: In this state, the neighboring routers are fully adjacent.
Mode
Neighbor mode for LSDB synchronization:
z
Nbr is Master: Means the neighboring router is the master.
z
Nbr is Slave: Means the neighboring router is the slave.
