Step Command

5.
Configure the dead
interval.
ospfv3 timer dead seconds [ instance
instance-id ]
Optional.
By default, the dead interval on P2P,
broadcast interfaces is 40 seconds.
The dead interval set on neighboring
interfaces cannot be too short;
otherwise, a neighbor is easily
considered down.
6.
Configure the LSA
retransmission interval.
ospfv3 timer retransmit interval
[ instance instance-id ]
Optional.
By default, the LSA retransmission
interval is 5 seconds.
The LSA retransmission interval
cannot be too short; otherwise,
unnecessary retransmissions will
occur.
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.

Configure a DR priority.
ospfv3 dr-priority priority [ instance

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.
