Setting the Interval at Which LSAs Are Updated

You can set the interval at which LSAs are updated based on network connections and router resources.

Context

On a stable network that requires fast route convergence, intelligent-timer needs to be specified in the lsa-originate-interval command to enable an intelligent timer to update OSPFv3 LSAs so that topology changes or route changes can be immediately advertised to the network through LSAs, which speeding up route convergence. This prevents too many network bandwidth and device resources from being consumed due to network connection changes or frequent route flapping.

Procedure

Run system-view
The system view is displayed.
Run ospfv3 [ process-id ]
The OSPFv3 process view is displayed.
Run 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 ] }
An intelligent timer is enabled to update OSPFv3 LSAs.
(Optional) Run lsa-originate-interval suppress-flapping interval [ threshold count ]
The suppression period that takes effect when the OSPFv3 LSAs to be sent flap is configured.

If no flapping occurs among the OSPFv3 LSAs to be sent, the configuration of the lsa-originate-interval command prevents the device from frequently sending LSAs. If the OSPFv3 LSAs to be sent flap, the configuration of the lsa-originate-interval suppress-flapping command minimizes the impact of the flapping on services. The larger value of the two intervals specified in the commands is used as the suppression period.
