Specifying The Lsa Arrival Interval; Specifying The Lsa Generation Interval; Disabling Interfaces From Receiving And Sending Ospf Packets - HP VSR1000 Configuration Manual

Specifying 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 configure the LSA arrival interval:
Step
1. Enter system view.
2. Enter OSPF view.
3. Configure the LSA arrival
interval.

Specifying the LSA generation interval

Adjust the LSA generation interval to protect network resources and routers from being overwhelmed by
LSAs at the time of frequent network changes.
When network changes are infrequent, LSAs are generated at the minimum-interval. If network changes
become frequent, the LSA generation interval is incremented by incremental-interval × 2
number of generation times) for each generation until the maximum-interval is reached.
To configure the LSA generation interval:
Step
1. Enter system view.
2. Enter OSPF view.
3. Configure the LSA
generation interval.

Disabling interfaces from receiving and sending OSPF packets

To enhance OSPF adaptability and reduce resource consumption, you can set an OSPF interface to
"silent." A silent OSPF interface blocks OSPF packets and cannot establish any OSPF neighbor
relationship. However, other interfaces on the router can still advertise direct routes of the interface in
Router LSAs.
