Parameters

process-id: Specifies an OSPF process by ID in the range of 1 to 65535. If you do not specify this argument, the command displays OSPF neighbor information for all OSPF processes.

verbose: Displays detailed neighbor information. If you do not specify this keyword, the command displays brief OSPF neighbor information.

interface-type interface-number: Specifies an interface by its type and number. If you do not specify this argument, the command displays neighbor information for all interfaces.

neighbor-id: Specifies a neighbor router ID. If you do not specify this argument, the command displays all neighbor information.

Examples

# Display detailed OSPF neighbor information.

Table 43: Command output

Field	Description
Area areaID interface IPAddress(InterfaceName)'s neighbors	Neighbor information for the interface in the specified area: areaID—Area to which the neighbor belongs. IPAddress—Interface IP address. InterfaceName—Interface name.
Router ID	Neighbor router ID.
Address	Neighbor router address.
GR state	GR state: Normal. Restarter. Complete. Helper.
State	Neighbor state: Down—Initial state of a neighbor conversation. Init—The router has received a Hello packet from the neighbor. However, the router has not established bidirectional communication with the neighbor. The router did not appear in the neighbor's hello packet. Attempt—Available only in an NBMA network. In this state, the OSPF router has not received any information from a neighbor for a period. The router can send Hello packets at a longer interval to keep the neighbor relationship. 2-Way—Communication between the two routers is bidirectional. The local router 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—The router is sending DD packets to the neighbor, describing its entire link-state database. Loading—The router sends LSRs packets to the neighbor, requesting more recent LSAs. Full—The neighboring routers are fully adjacent.
Mode	Neighbor mode for LSDB synchronization.
Priority	Neighboring router priority.
DR	DR on the interface's network segment.
BDR	BDR on the interface's network segment.
MTU	Interface MTU.
Options	LSA options: O—Opaque LSA advertisement capability. E—AS External LSA reception capability. EA—External extended LSA reception capability. DC—On-demand link support. N—NSSA external LSA support. P—Capability of an NSSA ABR to translate Type-7 LSAs into Type-5 LSAs.
Dead timer due in 33 sec	This dead timer will expire 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.
BFD status	BFD status: Disabled. Enabled (Control mode). Enabled (Echo mode).
Last Neighbor Down Event	The most recent neighbor down event.
Time	Time when the neighbor went down.
Reason	Reason for the neighbor down event.
