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.
NOTE:
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 × 2 n-2 (n is the number of
calculation times) each time a calculation occurs until the maximum-interval is reached.
Specifying the LSA arrival interval
After receiving the same LSA as the previously received LSA within the LSA arrival interval, OSPF discards
the LSA.
To configure the LSA arrival 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. Configure the LSA arrival
interval.
lsa-arrival-interval interval
Optional
1000 milliseconds by
default
NOTE:
The interval set with the lsa-arrival-interval command should be smaller than or equal to the interval set
with the lsa-generation-interval command.
Specifying the LSA generation interval
You can adjust the LSA generation interval to protect network resources and routers from being over
consumed due to frequent network changes.
To configure the LSA generation interval:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter OSPF view.
