Area areaID interface
IPAddress(InterfaceName)'s neighbors
Neighbor information of the interface in the specified area:
• areaID—Area to which the neighbor belongs.
• IPAddress—Interface IP address.
• InterfaceName—Interface name.
interface Interface attached with the neighbor.
Router ID Neighbor router ID.
Address Neighbor router address.
GR State GR state.
State
Neighbor state:
• 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 at 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.
Mode Neighbor mode for LSDB synchronization.
Priority Neighboring router priority.
DR The DR on the interface's network segment.
BDR The BDR on the interface’s network segment.
MTU Interface MTU.
Dead timer due in 33 sec Dead timer times out in 33 seconds.
Neighbor is up for 02:03:35 The neighbor has been up for 02:03:35.
Authentication Sequence Authentication sequence number.
Neighbor state change count Count of neighbor state changes.
