The ospfv3 timer dead command sets the dead interval of the OSPFv3 neighbor of the instance on the interface.
The undo ospfv3 timer dead command restores the default value.
By default, the dead interval of OSPFv3 neighbor is 40 seconds for the interface of P2P or Broadcast type. The dead interval of OSPFv3 neighbor is 120 seconds for the interface of P2MP or NBMA type.
ospfv3 timer dead interval [ instance instance-id ]
undo ospfv3 timer dead [ interval ] [ instance instance-id ]
| Parameter | Description | Value |
|---|---|---|
interval |
Indicates the dead interval of OSPFv3. |
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. |
Dead interval of OSPFv3 neighbor refers to that the neighbor is invalid if the neighbor does not receive the Hello packets from its neighbor in the interval. The dead interval of switches in the same network segment must be consistent.
Before running this command on an interface, run the ospfv3 area command on the interface to enable OSPFv3.
By default, the dead interval of OSPF neighbors is four times the Hello packet interval. After the Hello packet interval is configured in the instance of the interface using the ospfv3 timer hello command, the default dead interval of the OSPFv3 neighbor of the instance on the interface is changed to be four times the Hello packet interval.
