Set a tag for redistributed
routes.
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.
Setting OSPFv3 timers
Step
1.
Enter system view.
2.
Enter interface view.
3.
Set the hello interval.
4.
Set the dead interval.
5.
Set the poll interval.
6.
Set the LSA retransmission
interval.
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:
Step
1.
Enter system view.
Command
default tag tag
Command
system-view
interface interface-type
interface-number
ospfv3 timer hello seconds
[ instance instance-id ]
ospfv3 timer dead seconds
[ instance instance-id ]
ospfv3 timer poll seconds
[ instance instance-id ]
ospfv3 timer retransmit
interval [ instance

Remarks
By default, the tag of
redistributed routes is 1.
Remarks
N/A
N/A
By default, the hello interval on P2P and
broadcast interfaces is 10 seconds.
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.
By default, the poll interval is 120
seconds.
The default setting is 5 seconds.
The LSA retransmission interval cannot
be too short. Otherwise, unnecessary
retransmissions will occur.
