Specifying Lsa Transmission Delay; Specifying Spf Calculation Interval; Specifying The Lsa Arrival Interval - HP 3600 v2 series Configuration Manual

Specifying LSA transmission delay

Each LSA in the LSDB has an age that is incremented by 1 every second, but the age does not change
during transmission. It is necessary to add a transmission delay into the age time especially for low-speed
links.
Follow these steps to specify the LSA transmission delay on an interface:
To do...
Enter system view
Enter interface view
Specify the LSA transmission delay

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.
Follow these steps to configure SPF calculation interval:
To do...
Enter system view
Enter OSPF view

When network changes are not frequent, the

Specifying the LSA arrival interval

After receiving the same LSA as the previously received LSA within the LSA arrival interval, OSPF discards
the LSA.
Follow these steps to configure the LSA arrival interval:
