**Table 1** Description of the **display ospf** **graceful-restart** command output
Item	Description
Graceful-restart capability	Whether IETF GR is enabled: enabled disabled
Graceful-restart support	IETF GR mode that is supported currently: planned: indicates that only planned-GR is supported. planned and un-planned: indicates that both planned GR and unplanned GR are supported. totally: indicates that totally GR is supported. partial: indicates that partial GR is supported.
Helper-policy support	Policy that supports the Helper: planned: indicates that the Helper supports only planned GR. planned and un-planned: indicates the Helper supports both planned GR and unplanned GR. strict lsa check: indicates that the Helper supports strict external LSA check. ignore external lsa check: indicates that the Helper does not check external LSAs. never: indicates that the device does not support the Helper mode.
Current GR state	Current GR status: Normal: indicates that GR is in the Normal state. Under GR: indicates that the device enters the Restarter mode. Under Helper: indicates that the device enters the Helper mode.
Graceful-restart period	GR period.
Number of neighbors under helper	Number of neighbors in the Helper state: Normal neighbors: indicates the number of normal neighbors. Virtual neighbors: indicates the number of virtual neighbors. Sham-link neighbors: indicates the number of sham link neighbors. Total neighbors: indicates the total number of neighbors.
Number of restarting neighbors	Number of restarted devices displayed on the Helper.
Last exit reason	Reason why a device exits from GR last time: On graceful restart: indicates the reason that the Restarter exits from GR. On Helper: indicates the reason that the Helper exits from GR.
On graceful restart	Reason why the Restarter exits from GR: 1-way hello received: indicates that 1-way Hello packets are received. back-link check failed: indicates that the back link check fails. DR election fail: indicates that DR election fails. grace period expired: indicates that the GR period expires. interface state change: indicates that the interface state machine changes. none: indicates that the device never performs GR since startup. successful exit: indicates that the Restarter successfully exits from GR. two Grace-LSAs received: indicates that two Grace LSAs are received.
On Helper	Reason why the Helper exits from GR: flooding change LSA: indicates that the changed LSAs are received. grace period expired: indicates that the GR period expires. graceful restart unconfigured at process level: indicates that the GR function of the OSPF process is disabled. interface state change: indicates that the interface state machine changes. policy check failed for received grace LSA: indicates the policy that mismatches the Helper. received 1-way hello packet: indicates that 1-way Hello packets are received. received flushed grace LSA: indicates that flushed Grace LSAs are received. received multiple grace LSA: indicates that multiple Grace LSAs are received. neighbor reset: indicates that GR is disabled when neighbors are in the Helper mode. none: indicates that the device never enters the Helper mode since startup. successful exit: indicates that the Helper successfully exits from GR.

Type	Interface type: P2P P2MP NBMA Broadcast
Last Helper Exit reason	Reason why the neighbor exits from the Helper mode the last time: none: indicates that the device never enters the Helper mode since startup. successful exit: indicates that the neighbor successfully exits from the Helper mode. grace period expired: indicates that the GR period expires. received flushed grace LSA: indicates that flushed Grace LSAs are received. flooding change LSA: indicates that the changed LSAs are received. received multiple grace LSA: indicates that multiple Grace LSAs are received. received 1-way hello packet: indicates that 1-way Hello packets are received. policy check failed for received grace LSA: indicates the policy that mismatches the Helper. neighbor reset: indicates that the network topology changes after the reset command is run on the neighbor of the Helper. interface state change: indicates that the interface state machine changes. graceful restart unconfigured at process level: indicates that the neighbor is not configured with the GR function.
Neighbor count of this interface	Total number of neighbors of this interface.
Neighbor	Router ID of the neighbor.
IP address	IP address of the neighboring interface.
GR state	GR status of the neighbor: Normal: indicates that the neighbor is in the Normal state. Restarter: indicates that the neighbor enters the Restarter mode. Helper: indicates that the neighbor enters the Helper mode.
