GR State
GR state
State
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).
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
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.
Priority
Neighboring router priority
DR
The DR on the interface’s network segment
