ospfv3 timer wait

ospfv3 timer wait

Function

The ospfv3 timer wait command sets the wait timer on an OSPFv3 interface.

The undo ospfv3 timer wait command restores the wait timer on an OSPFv3 interface to the default value.

By default, for the interface of Broadcast and P2P, the wait interval is 40 seconds; for that of NBMA, it is 120 seconds.

Format

ospfv3 timer wait interval [ instance instance-id ]

undo ospfv3 timer wait [ interval ] [ instance instance-id ]

Parameters

Parameter Description Value
interval Specifies the timeout period of the wait timer on an OSPFv3 interface. The value is an integer ranging from 1 to 65535, in seconds.
instance instance-id Specifies the interface instance ID. The value is an integer ranging from 0 to 255. The default value is 0.

Usage Guidelines

Usage Scenario

You can run the ospfv3 timer wait command to change the timeout period of the wait timer. If no Backup Seen event is received within the timeout period, the designated router (DR) election starts. Setting a proper value for the wait timer can decrease the frequency of changes of the DR and the backup designated router (BDR) on the network, reducing network flapping. When setting the wait timer, note the following points:

  • The wait timer takes effect only on broadcast interfaces.

  • The value of the wait timer cannot be greater than the value of the dead timer.

Prerequisites

OSPFv3 has been enabled on the interface using the ospfv3 area command.

Precautions

OSPFv3 does not support the configuration on a null interface.

# Set the wait timer on Vlanif10 to 30 seconds.
