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 default value.

By default, on broadcast and P2P interfaces, the wait interval is 40 seconds; on NBMA interfaces, 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 wait timer on an OSPFv3 interface.	The value is an integer ranging from 1 to 65535, in seconds.
instance instance-id	Specifies an interface instance ID.	The value is an integer ranging from 0 to 255. The default value is 0.

Usage Guidelines

Usage Scenario

To change the wait timer, run the ospfv3 timer wait command. If no Backup Seen event is received within the timer, the designated router (DR) election starts. Setting a proper value for the wait timer can slow down 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 and NBMA interfaces.
The value of the wait timer cannot be greater than the value of the dead timer.

Precautions

The command cannot be run on null interfaces.

Example

# Set the wait timer on GE 0/1/0 to 30 seconds.
