Usage Guidelines

In addition to OSPF brief information, running this command also displays the following information:

Configured Router ID
Configured VPN domain ID

When locating OSPF faults, you can run the display ospf brief command to obtain OSPF brief information. You can then analyze OSPF faults according to the brief information.

Example

**Table 1** Description of the **display ospf** **brief** command output
Item	Description
RouterID	Current router ID.
Border Router	Border router: AS: autonomous system border router (ASBR). AREA: area border router (ABR). NSSA: ABR of an NSSA.
Multi-VPN-Instance is not enabled	The current process does not support multi-VPN-instance.
Opaque Capable	Opaque-LSA capability is enabled. To enable the Opaque-LSA capability, run the opaque-capability enable command.
Global DS-TE Mode	Globally configured DS-TE mode: Non-Standard IETF Mode: The IETF mode is not supported. Standard IETF Mode: The IETF mode is supported.
Graceful-restart capability	Whether graceful restart is enabled: disabled: Graceful restart is disabled. planned only: Planned-GR is supported. un-planned: Unplanned-GR is supported. totally: Totally GR is supported. planned and un-planned: Planned-GR and unplanned-GR are supported. To enable the GR function, run the graceful-restart (OSPF) command.
Helper support capability	Whether the Helper mode is enabled: enabled: The Helper mode is enabled. not configured: The Helper mode is disabled. To configure a device as a GR helper, run the graceful-restart helper-role (OSPF) command.
filter capability	Whether the filtering rule of the Helper mode is enabled: ip-prefix: The IP prefix filtering rule of the Helper mode is enabled. acl-number: The basic ACL filtering rule of the Helper mode is enabled. acl-name: The named ACL filtering rule of the Helper mode is enabled. disabled: The filtering rule of the Helper mode is disabled.
policy capability	Whether a policy is configured for the Helper mode: strict lsa check: The Helper checks all LSAs. To prevent the Helper from checking AS external LSAs, run the graceful-restart helper-role ignore-external-lsa command. ignore external lsa check: The Helper does not check AS external LSAs. planned and un-planned: The Helper supports planned-GR and unplanned-GR. To configure the Helper to support only planned-GR, run the graceful-restart helper-role planned-only command. planned: The Helper supports only planned-GR.
Applications Supported: MPLS Traffic-Engineering	OSPF supports Traffic Engineering (TE).
Spf-schedule-interval	Interval for performing SPF calculation. To set the interval for OSPF to calculate routes, run the spf-schedule-interval command.
Route Preference	Preference of the default route.
ASE Route Preference	Priority of the external route.
Default ASE parameters	Default parameters of the external LSA. Metric: default metric of the external LSA. Tag: default tag of the external LSA. Type: default type of the external LSA.
SPF Computation Count	Number of times that SPF calculation is performed.
RFC 1583 Compatible	Whether RFC 1583 compatibility is enabled. To convert rules defined in RFC 2328 into rules defined in RFC 1583, run the rfc1583 compatible command.
Retransmission limitation is disabled	Retransmission limit is disabled. To enable retransmission limit and set the maximum number of retransmissions, run the retransmission-limit command.
Import routes limitation is enabled, the maximal limitation value	Maximum number of imported routes is restricted and that the maximum value is displayed.
Area Count	Number of areas in the current process.
Nssa Area Count	Number of NSSAs in the current process.
Process total up interface count	Number of interfaces that are up.
Process valid up interface count	Number of interfaces that are valid.
Flush protect mode	Whether master/slave board switching triggered by abnormal OSPF LSA aging is enabled: false: Master/Slave board switching triggered by abnormal OSPF LSA aging is disabled. true: Master/Slave board switching triggered by abnormal OSPF LSA aging is enabled.
ExChange/Loading Neighbors	Number of neighbors in the ExChange/Loading state.
Area	Information about each area in the current process, including ID of the current area in dotted decimal notation.
Authtype	Area authentication type, including none-authentication, simple authentication, MD5 authentication, HMAC-SHA256 authentication, and HMAC-MD5 authentication.
Area flag	Flag used to describe the area attributes, including Transit/Vlink/Stub/Nssa/Normal.
SPF scheduled Count	Number of times that SPF calculation is performed.
Interface	Interface information in the area.
Cost	Cost of an OSPF interface. To set the cost for an OSPF on an interface, run the ospf cost command.
State	Interface status: Down Waiting Loopback P-2-P DR BDR DROTHER DR and BDR DROTHER exist in only broadcast and NBMA networks, and P-2-P exists in only P2P and P2MP Vlinks.
Type	Interface type, including P2P, broadcast, NBMA, and P2MP.
MTU	MTU value of the interface.
Priority	Interface priority.

Timers	Interval of the timer.
Hello	Interval of the Hello timer. To set the interval for sending Hello packets on an interface, run the ospf timer hello command.
Dead	Interval of the Dead timer. To set the dead interval after which an interface considers its OSPF neighbor invalid, run the ospf timer dead command.
Poll	Interval of the Poll timer. To set the poll interval for sending Hello packets on NBMA networks, run the ospf timer poll command.
Retransmit	Interval of the Retransmit timer. To set the interval for retransmitting LSA on an interface, run the ospf timer retransmit command.
Transmit Delay	(Optional) delay for transmitting LSAs on the interface. To add the transmission delay to LSAs before they are sent by an interface, run the ospf trans-delay command.
Router ID conflict state	Status of the automatic recovery function. The value can be one of the following: Normal: The automatic recovery function is properly detecting router ID conflict. Wait select: The automatic recovery function delays defining a new router ID if the device starts after an unexpected delay (two hours by default). Selecting: The automatic recovery function restarts the OSPF process with the router ID and waits for the restarted OSPF process to take effect. RtrId Changed: The automatic recovery function determines whether router ID conflict occurs after the new router ID takes effect and returns to the Normal state if no new router ID conflict is detected. Suspend: If the maximum number of conflict times is reached, automatic recovery function does not define a new router ID any longer. The maximum number of conflict times is three by default.
Area interface up count	The number of interfaces up in the area.
