Field Description
State
State of a neighbor:
Down: This is the initial state of a neighbor conversation.
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).
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.
2-Way: In this state, communication between the two routers is
bidirectional. The router itself appears in the neighbor's Hello packet.
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.
Exchange: In this state, the router is sending DD packets to the
neighbor, describing its entire link-state database.
Loading: In this state, the router sends Link State Request packets to the
neighbor, requesting more recent LSAs.
Full: In this state, the neighboring routers are fully adjacent.
