Parameters

process-id: Specifies an OSPFv3 process by its ID in the range of 1 to 65535. If you do not specify a process, this command displays neighbor information for all processes.

area area-id: Specifies an area by its ID, an IPv4 address or a decimal integer in the range of 0 to 4294967295 that is translated into the IPv4 address format. If you do not specify an area, this command displays neighbor information for all areas.

interface-type interface-number: Specifies an interface by its type and number.

verbose: Displays detailed neighbor information.

peer-router-id: Specifies a neighbor.

statistics: Displays OSPFv3 neighbor statistics.

Usage guidelines

If you do not specify an interface and a neighbor, this command displays neighbor information for all interfaces.

Table 156: Command output

Field	Description
Area ID	Area ID.
Down	In this state, neighbor initial state, the router has not received any information from a neighboring router for a period of time.
Attempt	This state is available only in an NBMA network. In this state, the OSPFv3 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.
Init	In this state, the device received a Hello packet from the neighbor but the packet contains no router ID of the neighbor. Mutual communication is not setup.
2-Way	Mutual communication between the router and its neighbor is available. DR/BDR election is finished under this state (or higher).
ExStart	In this state, the router decides on the initial DD sequence number and active/standby relationship of the two parties.
Exchange	In this state, the router exchanges DD packets with the neighbor.
Loading	In this state, the router sends LSRs to request the neighbor for needed LSAs.
Full	LSDB synchronization has been accomplished between neighbors.
Total	Total number of neighbors under the same state.
