lsa-originate-interval (OSPFv3)

lsa-originate-interval (OSPFv3)

Function

The lsa-originate-interval command sets the interval for updating OSPFv3 LSAs .

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.

Format

lsa-originate-interval { 0 | intelligent-timer max-interval start-interval hold-interval [ other-type interval ] | other-type interval [ intelligent-timer max-interval start-interval hold-interval ] }

lsa-originate-interval suppress-flapping suppress-interval

undo lsa-originate-interval

undo lsa-originate-interval suppress-flapping

Parameters

Parameter Description Value
0 Not set the interval for updating OSPFv3 LSAs -
intelligent-timer Sets the interval for updating OSPFv3 Type 1 Router-LSAs, Tpe 2 Network-LSAs, Type5 AS-external-LSAs, Type7 NSSA LSAs, and Type 8 Link-LSAs by using an intelligent timer. -
max-interval Specifies the maximum interval for updating OSPFv3 LSAs. The value ranges from 1 to 120000, in milliseconds. The default value is 5000.
start-interval Specifies the initial interval for updating OSPFv3 LSAs. The value ranges from 0 to 60000, in milliseconds. The default value is 500.
hold-interval Specifies the hold interval for updating OSPFv3 LSAs. The value ranges from 1 to 60000, in milliseconds. The default value is 1000.
other-type Specify an interval for Type-3, Type-4 and Type-9 LSAs. -
interval Specifies the interval of backup. The value ranges from 0 to 10, in seconds. The default value is 5.
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.

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.

The lsa-originate-interval suppress-flapping command specifies the maximum OSPFv3 LSA suppression period. If the OSPFv3 LSAs to be sent flap, the larger value of the two intervals specified in the commands is used as the suppression period.

Example

# Set the maximum interval for updating OSPFv3 LSAs to 10000 ms, the initial interval to 700 ms, and the hold interval to 4000 ms.
