• LSA delay timer—Specified especially for low-speed links.
• SPF timer—Specified to protect networks from being over-loaded due to frequent network changes.
For a broadcast network, you can configure DR priorities for interfaces to affect DR/BDR election.
After an interface is disabled from sending OSPFv3 packets, other routers cannot obtain any information
from the interface.
Configuration prerequisites
Before you tune and optimize OSPFv3 networks, complete the following tasks:
• Enable IPv6.
• Configure OSPFv3 basic functions.
Configuring OSPFv3 timers
To configure OSPFv3 timers:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter interface view.
interface interface-type
interface-number
N/A
3. Configure the hello interval.
ospfv3 timer hello seconds
[ instance instance-id ]
Optional.
Defaults to 10 seconds on P2P,
broadcast interfaces.
4. Specify the poll interval.
ospfv3 timer poll seconds
[ instance instance-id ]
Optional.
The poll interval defaults to 120
seconds.
5. Configure the dead interval.
ospfv3 timer dead seconds
[ instance instance-id ]
Optional.
Defaults to 40 seconds on P2P,
broadcast interfaces.
6. Configure the LSA
retransmission interval. ospfv3 timer retransmit interval
[ instance instance-id ]
Optional.
Defaults to 5 seconds.
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. quit N/A
9. Enter OSPFv3 view. ospfv3 [ process-id ] N/A
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.
