display ospfv3 peer

Function

The display ospfv3 peer command displays specified OSPFv3 neighbors.

Format

display ospfv3 [ process-id ] [ area { area-id | area-id } ] peer [ { neighbor-id | hostname hostnamestr } | interfaceName | interfaceType interfaceNum ] [ verbose ]

display ospfv3 [ process-id ] peer last-nbr-down

display ospfv3 [ process-id ] [ area { area-id | area-id } ] peer [ neighbor-id | interfaceName | interfaceType interfaceNum ] resolve-hostname [ verbose ]

Parameters

Parameter	Description	Value
process-id	Specifies an OSPFv3 process ID.	The value is an integer ranging from 1 to 4294967295.
area area-id	Specifies an area ID.	The value can be a decimal integer or in the IPv4 address format. The integer ranges from 0 to 4294967295.
neighbor-id	Specifies router ID of a neighbor.	The value is in dotted decimal notation.
hostname hostnamestr	Specifies a dynamic hostname.	The value is a string of 1 to 255 characters.
interfaceName	Indicates the name of an interface.	-
interfaceType	Indicates the type of an interface.	-
interfaceNum	Indicates the number of an interface.	The value is a string of 1 to 63 case-sensitive characters, spaces not supported.
verbose	Displays detailed information of neighbors of each area.	-
last-nbr-down	Displays the brief information about the last neighbor that goes Down in an OSPFv3 process. A maximum of the last ten neighbors that go Down can be displayed for each process.	-
resolve-hostname	Displays information about resolved dynamic hostnames.	-

Usage Guidelines

Usage Scenario

The command output can display information about OSPFv3 neighbors, and help you troubleshoot OSPFv3 faults, verify the configurations of OSPFv3 neighbors, and check whether the neighbor performs Graceful Restart (GR).

Example

The actual command output varies according to the device. The command output here is only an example.
