Default Hello and Dead timer values will be restored once the network type is changed.

Do not set an LSA retransmission interval that is too short. Otherwise, unnecessary retransmission 

will occur. LSA retransmission interval must be greater than the round trip time of a packet between 

two routers. 

 

Follow these steps to configure the LSA transmission delay: 

Enter system view 

— 

Enter interface view  

interface interface-type 
interface-number 

— 

Configure the LSA 
transmission delay 

ospf trans-delay seconds 

Required 

1 second by default 

 

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.  

 

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 affect caused by frequent network 

changes. 

Follow these steps to configure the SPF calculation interval: 

Enter system view 

— 

Enter OSPF view 

ospf [ process-id [ router-id 
router-id ] ]
