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. |
