Specifying SPF calculation interval
LSDB changes result in SPF calculations. When the topology changes frequently, a large amount of network and router resources are occupied by SPF calculation. You can adjust the SPF calculation interval to reduce the impact.
When network changes are not frequent, the minimum-interval is adopted. If network changes become frequent, the SPF calculation interval is incremented by incremental-interval × 2n-2 (n is the number of generation times) each time an SPF calculation occurs until the maximum-interval is reached.
To configure SPF calculation interval:
Step | Command | Remarks |
---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter OSPFv3 view. | ospfv3 [ process-id | vpn-instance vpn-instance-name ] * | N/A |
3. Specify the SPF calculation interval. | spf-schedule-interval maximum-interval [ minimum-interval [ incremental-interval ] ] | By default:
