Configuring The Spf Calculation Interval; Disabling Ospf Packet Transmission On An Interface - Huawei Quidway S5600 Series Operation Manual

Operation Manual – Routing Protocol
Quidway S5600 Series Ethernet Switches-Release 1510
Note:
The transmission of OSPF packets on a link also takes time. Therefore, a transmission
delay should be added to the aging time of LSAs before the LSAs are transmitted. For a
low-speed link, pay close attention on this configuration.

4.7.4 Configuring the SPF Calculation Interval

Whenever the LSDB of OSPF is changed, the shortest paths need to be recalculated.
When the network changes frequently, calculating the shortest paths immediately after
LSDB changes will consume enormous resources and affect the operation efficiency of
the router. By adjusting the minimum SPF calculation interval, you can lighten the
negative affection caused by frequent network changes.

4.7.5 Disabling OSPF Packet Transmission on an Interface

To prevent OSPF routing information from being acquired by the routers on a certain
network, use the silent-interface command to disable OSPF packet transmission on
the corresponding interface.
