Tuning and optimizing OSPFv3 networks
This section describes configurations of OSPFv3 timers, interface DR priority, and the logging of
neighbor state changes.
Configuration prerequisites
Before you tune and optimize OSPFv3 networks, perform the following tasks:
•
Configure IPv6 addresses for interfaces to ensure IPv6 connectivity between neighboring
nodes.
•
Enable OSPFv3.

3.
Set the hello interval.
ospfv3 timer hello
seconds
[
instance instance-id
]
By default, the hello interval on P2P and
broadcast interfaces is 10 seconds.
4.
Set the dead interval.
ospfv3 timer dead
seconds
[
instance instance-id
]
By default, the dead interval on P2P and
broadcast interfaces is 40 seconds.
The dead interval set on neighboring
interfaces cannot be too short.
Otherwise, a neighbor is easily
considered down.
5.
Set the poll interval.
ospfv3 timer poll
seconds
[
instance
instance-id
]
By default, the poll interval is 120
seconds.
6.
Set the LSA retransmission
interval.
ospfv3 timer retransmit
interval
[
instance
instance-id
]
The default setting is 5 seconds.
The LSA retransmission interval cannot
be too short. Otherwise, unnecessary
retransmissions will occur.
Setting LSA transmission delay
Each LSA in the LSDB has an age that is incremented by 1 every second, but the age does not
change during transmission. Therefore, it is necessary to add a transmission delay into the age time,
especially for low-speed links.
To set the LSA transmission delay on an interface:
