State
State of a neighbor:
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).
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 2-Way: In this state, communication between the two routers is
bidirectional. The router itself appears in the neighbor's Hello packet.
z Exstart: The goal of this state is to decide which router is the master,
and to decide upon the initial Database Description (DD) sequence
number.
z Exchange: In this state, the router is sending DD packets to the
neighbor, describing its entire link-state database.
z Loading: In this state, the router sends Link State Request packets to
the neighbor, requesting more recent LSAs.
z Full: In this state, the neighboring routers are fully adjacent.
Mode Master/Slave mode formed by negotiation in exchanging DD packet
Priority Priority of DR/BDR for neighbor election
DR DR in the subnet the interface is attached to
