lsa-originate-interval (OSPFv3)

Function

The lsa-originate-interval command sets the interval for updating OSPFv3 LSAs by using an SPF intelligent timer.

The undo lsa-originate-interval command restores the default setting.

By default, the interval for updating OSPFv3 LSAs is the default value of the SPF intelligent timer.

Parameters

Parameter	Description	Value
intelligent-timer	Sets the interval for updating OSPFv3 Type 1 Router-LSAs, Type 2 Network-LSAs, and Type 8 Link-LSAs by using an intelligent timer.	-
lsa-originate-max-interval	Specifies the maximum interval for updating OSPFv3 LSAs.	The value ranges from 1 to 10000, in milliseconds. The default value is 5000.
lsa-originate-start-interval	Specifies the initial interval for updating OSPFv3 LSAs.	The value ranges from 0 to 1000, in milliseconds. The default value is 500.
hold-interval	Specifies the hold interval for updating OSPFv3 LSAs.	The value ranges from 1 to 5000, in milliseconds. The default value is 1000.
suppress-flapping suppress-interval	Specifies the maximum OSPFv3 LSA suppression period.	The value is an integer ranging from 0 to 600, in seconds. The default value is 10 seconds. If the value is set to 0, OSPFv3 LSAs are not suppressed.
threshold count	Specifies an OSPFv3 LSA suppression threshold.	The value is an integer ranging from 3 to 100. The default value is 30.

Usage Guidelines

On a stable network where routes need to be fast converged, the parameter intelligent-timer needs to be specified to set the interval for updating LSAs (in milliseconds) so that topology changes or route changes can be immediately advertised to the network by using LSAs. In this manner, route convergence can be speeded up. This prevents too many network bandwidths and device resources from being consumed due to network connections or frequent route flapping.

To configure the maximum OSPFv3 LSA suppression period, run the lsa-originate-interval suppress-flapping command. If frequent OSPFv3 LSA flapping occurs, the larger value between lsa-originate-interval suppress-flapping and lsa-originate-interval is used to suppress OSPFv3 LSA flapping.

The flapping of Router-LSAs, Network-LSAs, and Link-LSAs is not suppressed.

The flapping of MaxAge Router LSAs is not suppressed.
