Setting LSA transmission delay
To avoid LSAs from aging out during transmission, set an LSA retransmission delay especially for
low speed links.
To set the LSA transmission delay on an interface:
Step Command Remarks
1. Enter system view.
system-view N/A
2. Enter interface view.
interface interface-type
interface-number
N/A
3. Set the LSA transmission
delay.
ospf trans-delay
seconds The default setting is 1 second.
Setting 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.
For a stable network, the minimum interval is used. If network changes become frequent, the SPF
calculation interval is incremented by the incremental interval × 2
n-2
for each calculation until the
maximum interval is reached. The value n is the number of calculation times.
To set the SPF calculation interval:
Step Command Remarks
1. Enter system view.
system-view
N/A
2. Enter OSPF view.

3. Set the SPF
calculation interval.

[ incremental-interval ] ]
By default:
•
The maximum interval is 5
seconds.
•
The minimum interval is 50
milliseconds.
•
The incremental interval is 200
milliseconds.
Setting the LSA arrival interval
If OSPF receives an LSA that has the same LSA type, LS ID, and router ID as the previously received
LSA within the LSA arrival interval, OSPF discards the LSA to save bandwidth and route resources.
To set the LSA arrival interval:
Step Command Remarks
1. Enter system view.
