Configuration Prerequisites; Configuring Ospfv3 Timers - HPE 5800 Series Configuration Manual

Configuration prerequisites

Before you tune and optimize OSPFv3 networks, complete the following tasks:
•
Enable IPv6 packet forwarding.
•
Configure OSPFv3 basic functions.

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:
Step
Enter system view.
1.
Enter interface view.
2.
Configure the hello interval.
3.
Specify the poll interval.
4.
Configure the dead interval.
5.
Configure the LSA
6.
retransmission interval.
Configure the LSA
7.
transmission delay.
Return to system view.
8.
Enter OSPFv3 view.
9.
10. Configure the SPF timers.

N/A
Optional.
By default, the hello interval is 10
seconds on P2P and broadcast
interfaces.
Optional.
By default, the poll interval is 120
seconds.
Optional.
By default, the dead interval is 40
seconds on P2P and broadcast
interfaces.
Optional.
By default, the LSA
retransmission interval is 5
seconds.
Optional.
By default, the LSA transmission
delay is 1 second.
N/A
N/A
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.
