Configuration prerequisites
Before tuning and optimizing OSPFv3 networks, complete the following tasks:
• Enable IPv6 packet forwarding
• Configure OSPFv3 basic functions
Configuring OSPFv3 timers
Follow these steps to configure OSPFv3 timers:
To do… Use the command… Remarks

Configure the hello interval
ospfv3 timer hello seconds
[ instance instance-id ]
Optional
Defaults to 10 seconds on P2P,
broadcast interfaces.
Specify the poll interval
ospfv3 timer poll seconds
[ instance instance-id ]
Optional
The poll interval defaults to 120
seconds.
Configure the dead interval
ospfv3 timer dead seconds
[ instance instance-id ]
Optional
Defaults to 40 seconds on P2P,
broadcast interfaces.
Configure the LSA retransmission
interval ospfv3 timer retransmit interval
[ instance instance-id ] Optional
Defaults to 5 seconds.
Configure the LSA transmission
delay ospfv3 trans-delay seconds
[ instance instance-id ] Optional
Defaults to 1 second.
Return to system view quit —
Enter OSPFv3 view ospfv3 [ process-id ] —
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.
NOTE:
•
If the dead interval set on neighboring interfaces is too short, a neighbor can easily be considered
down.
• If the LSA retransmission interval is too short, unnecessary retransmissions will occur.
