Configuring OSPFv3 timers
Make sure that the dead interval set on neighboring interfaces is not too short; otherwise, a neighbor is
easily considered down. Also, make sure that the LSA retransmission interval is not too short; otherwise,
unnecessary retransmissions might occur.
To configure OSPFv3 timers:

Remarks
1. Enter system view.

2. Enter interface view.

3. Configure the hello
interval.
ospfv3 timer hello seconds
[ instance instance-id ]
Optional.
By default, the hello interval is 10 seconds on
P2P and broadcast interfaces.
4. Specify the poll
interval.
ospfv3 timer poll seconds
[ instance instance-id ]
Optional.
By default, the poll interval is 120 seconds.
5. Configure the dead
interval.
ospfv3 timer dead seconds
[ instance instance-id ]
Optional.
By default, the dead interval is 40 seconds on
P2P and broadcast interfaces.
6. Configure the LSA
retransmission interval.
ospfv3 timer retransmit
interval [ instance
instance-id ]
Optional.
By default, the LSA retransmission interval is 5
seconds.
7. Configure the LSA
transmission delay.
ospfv3 trans-delay seconds
[ instance instance-id ]
Optional.
By default, the LSA transmission delay is 1
second.
8. Return to system view.

10. Configure the SPF
timers.
spf timers delay-interval
hold-interval
Optional.
By default, delay-interval is 5 seconds, and
hold-interval is 10 seconds.
Setting both the delay-interval and hold-interval
to 0 triggers an SPF calculation at once,
improving the network convergence speed.
Configuring a DR priority for an interface
The DR priority of an interface determines the interface's qualification in DR election. Interfaces having
the priority 0 cannot become a DR or BDR.
