RouterID

Router ID.

Border Router

Border router:

• AS: autonomous system border router (ASBR)

• AREA: area border router (ABR)

• NSSA: ABR of an NSSA

Route Tag

Tag associated with the external route.

Multi-VPN-Instance

Whether VPN multi-instance is enabled.

Opaque Capable

Opaque-LSA capability is enabled. If Opaque-LSA capability is not enabled, run the opaque-capability enable command.

Graceful-restart capability

Whether graceful restart is enabled:

• disabled: Graceful restart is disabled. You can run the graceful-restart command to enable it.

• 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.

Helper support capability

Whether the Helper mode is enabled:

• enabled: The Helper mode is enabled.

• not configured: The Helper mode is disabled. You can run the graceful-restart helper-role command to enable it.

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.
• 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

Functions supported by OSPF. MPLS Traffic-Engineering indicates that OSPF supports TE.

Spf-schedule-interval

SPF calculation interval.

Default ASE parameters

Default parameters in external LSAs:

• Metric: cost
• Tag: route tag
• Type: route type

Route Preference

Priority of the default route.

ASE Route Preference

Priority of the external route.

SPF Computation count

Number of times that SPF calculation is performed.

RFC1583 Compatible

Rules in RFC 2328 are configured to be compatible with those defined in RFC 1583. If such configuration is not performed, run the rfc1583 compatible command.

Retransmission limitation

Whether a retransmission limit is configured.

Import routes limitation

Whether a limit on the number of external routes that can be imported is configured.

the maximal limitation value

Maximum number of external routes that can be imported.

Area Count

Number of areas in the process.

Nssa Area Count

Number of NSSAs in the process.

ExChange/Loading Neighbors

Number of neighbors in ExChange and Loading states.

Area

Area ID.

MPLS TE

Whether MPLS TE is enabled.

Authtype

Area authentication types:

• null: non-authentication mode
• simple: simple authentication
• MD5: MD5 ciphertext authentication
• HMAC-MD5: HMAC-MD5 authentication
• HMAC-SHA256: HMAC-SHA256 authentication

Area flag

Area attributes:

• Normal: common area
• Vlink: transit area of the virtual link
• Stub: Stub area
• Nssa: NSSA

SPF scheduled Count

Number of times that SPF calculation is performed.

Router ID conflict state

Status of the router ID auto-recovery state machine:

• Normal: The auto-recovery function is properly detecting router ID conflicts.
• Wait select: A new router ID is reselected if the device starts after an unexpected delay (two hours by default).
• Selecting: A new router ID is reselected and ready to take effect after an OSPF process is restarted.
• RtrId Changed: The auto-recovery function determines whether a router ID conflict occurs when the new router ID takes effect.
  • A new router ID is reselected if a router ID conflict is detected.
  • The auto-recovery state machine returns to Normal if no router ID conflict is detected.
• Suspend: No new router IDs are reselected any more if the number of conflict times reaches the maximum value (three times by default).

Interface

Interface information in the area.

Cost

Cost of an OSPF interface.

State

Interface status, which can be Down, Waiting, Loopback, P-2-P, DR, BDR, or DR OTHER. DR, BDR, and DR OTHER exist only on broadcast and NBMA networks, and P-2-P exists only on P2P and P2MP networks.

Type

Interface types:

• PTP: P2P
• Broadcast
• NBMA
• PTMP: P2MP

MTU

MTU value of the interface.

Priority

Interface priority.

Designated Router

Interface of the DR.

Backup Designated Router

Interface of the BDR.

Timers

Timer intervals:

• Hello: interval at which an interface sends Hello packets, which can be set using the ospf timer hello command.
• Dead: OSPF neighbor dead interval, which can be set using the ospf timer dead command.
• Poll: interval at which poll Hello packets are sent on NBMA networks, which can be set using the ospf timer poll command.
• Retransmit: interval at which an interface retransmits LSAs, which can be set using the ospf timer retransmit command.
• Transmit Delay: LSA transmission delay, which can be set using the ospf trans-delay command.
