Specifying SPF calculation interval
LSDB changes lead to SPF calculations. When the topology changes frequently, a large amount of network and router resources are occupied by SPF calculation. 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 calculation times) each time a 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 OSPF view. | ospf [ process-id | router-id router-id | vpn-instance vpn-instance-name ] * | N/A |
3. Specify the SPF calculation interval. | spf-schedule-interval maximum-interval [ minimum-interval [ incremental-interval ] ] | Optional. By default, the interval is 5 seconds. |
