Field	Description
OSPF Process 1 with Router ID 1.1.1.1 Graceful Restart information	GR information for OSPF process 1 with router ID 1.1.1.1.
Graceful Restart capability	Whether GR is enabled: Enable(IETF)—IETF GR is enabled. Enable(Nonstandard)—Non-IETF GR is enabled. Disable—GR is disabled.
Graceful Restart support	GR modes that the process supports (displayed only when GR is enabled): Planned and un-planned—Supports both planned and unplanned GR. Planned only—Supports only planned GR. Partial—Supports partial GR. Global—Supports global GR.
Helper capability	Helper capability that the process supports: Enable (IETF)—Supports IETF GR helper capability. Enable (Nonstandard)—Supports non-IETF GR helper capability. Enable (IETF and nonstandard)—Supports both IETF GR helper capability and non-IETF GR helper capability. Disable—Does not support GR helper capability.
Helper support	Policies that the helper supports (displayed only when GR helper is enabled): Strict lsa check—The helper supports strict LSA checking. Planned and un-planned—The helper supports planned and unplanned GR. Planned only—The helper supports only planned GR.
Current GR state	GR state: Normal—GR is not in progress or has completed. Under GR—GR is in process. Under Helper—The process is acting as GR helper.
Last exit reason	Last exit reason: Restarter—Reason that the restarter exited most recently. Helper—Reason that the helper exited most recently.
Area	Area ID in IP address format.
Authtype	Authentication type of the area: None—No authentication. Simple—Simple authentication. MD5—MD5 authentication. Keychain—Keychain authentication.
Area flag	Type of the area: Normal. Stub. StubNoSummary (totally stub area). NSSA. NSSANoSummary (totally NSSA area).
Area up Interface count	Number of up interfaces in the area.
Interface	Interface in the area.
Restarter state	Restarter state on the interface.
State	Interface state.
Type	Interface network type.
Neighbor count of this interface	Neighbors of an interface.
Neighbor	Neighbor router ID.
IP address	Neighbor IP address.
GR state	Neighbor GR state: Normal—GR is not in progress or has completed. Under GR—GR is in process. Under Helper—The process is acting as GR helper.
Last Helper exit reason	Reason that the helper exited most recently.
Virtual-link Neighbor-ID	Router ID of the virtual link's neighbor.
Neighbor-State	Neighbor state: Down, Init, 2-Way, ExStart, Exchange, Loading, and Full.
Interface	Output interface of the virtual link.
