910BConfiguring 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:

1141. 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.
1142. Specify the poll interval.
ospfv3 timer poll seconds
[ instance instance-id ]
Optional.
By default, the poll interval is120
seconds.
1143. 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.
1144. Configure the LSA
retransmission interval.
ospfv3 timer retransmit
interval [ instance
instance-id ]
Optional.
By default, the LSA retransmission
interval is 5 seconds.
1145. Configure the LSA
transmission delay.
ospfv3 trans-delay seconds
[ instance instance-id ]
Optional.
By default, the LSA transmission delay is
1 second.
1146. Return to system view.

1148. 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.
911BConfiguring 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.
To configure a DR priority for an interface:
