**Table 1** Description of the **display ospfv3 area** command output
Item	Description
Area BACKBONE(0) Status	Area status. up: OSPFv3 is active in this area. down: OSPFv3 is inactive in this area.
Area Bdr Router count	Number of Area Border Routers (ABRs) in the area.
Area ASBdr Router count	Number of AS Boundary Routers (ASBRs) in the area.
Number of interfaces in this area	Number of active interfaces.
Number of LSA	Number of Link State Advertisements (LSAs) in this area.
Number of Unknown LSA	Number of unknown LSAs in the area.
SPF algorithm executed	Number of Shortest Path First (SPF) calculations.
Checksum	Area checksum.
Router ID conflict state	Router ID conflict state. Normal: No router ID conflicts exist. Wait select: A new router ID is to be selected. Selecting: A new router ID is being selected. RtrId Changed: The router ID has been changed. Suspend: Automatic recovery from the OSPF router ID conflict is suspended because of a process reset. NA: The state is not reported.
Authentication	HMAC-SHA256 authentication mode which can be configured using the authentication-mode (OSPFv3) command.
Next SPF Trigger Time	Delay in SPT calculation after the topology changes.
Import routes limitation	Whether a limit is configured on the number of LSAs generated when an OSPFv3 process imports external routes.
Self NSSA LSA count	Number of existing NSSA LSAs. This field is displayed only in an OSPFv3 process.
Current status	A limit has been configured on the number of LSAs generated when an OSPFv3 process imports external routes. The current status can be as follows: Normal: The number of LSAs generated when an OSPFv3 process imports external routes is less than or equal to the lower alarm threshold (in percentage) multiplied by the maximum number allowed. Approach limit: The number of LSAs generated when an OSPFv3 process imports external routes is approaching (reaching or exceeding 90% of) the upper alarm threshold. Exceed limit: The number of LSAs generated when an OSPFv3 process imports external routes has reached or exceeded the maximum number allowed. To configure the upper and lower alarm thresholds, run the import-route limit command.
