Configuring OSPFv3 timers

1. Enter system view.

system-view

N/A

2. Enter interface view.

interface interface-type interface-number

N/A

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.
