The ospf timer dead multi-area command configures a dead interval of OSPF neighbor relationships for a multi-area adjacency interface.
The undo ospf timer dead multi-area command restores the default dead interval.
By default, the dead interval of OSPF neighbor relationships on a P2P multi-area adjacency interface is 40s.
| Parameter | Description | Value |
|---|---|---|
| interval |
Specifies the dead interval of OSPF neighbor relationships. |
The value is an integer ranging from 1 to 235926000, in seconds. Setting a value that is larger than 20 for the interval is recommended. If the interval is less than 20s, adjacencies may be interrupted. |
| area-id |
Specifies the ID of an OSPF area. |
The value can be a decimal integer ranging from 0 to 4294967295 or in the format of an IP address. |

Usage Scenario
If an interface does not receive Hello packets from an OSPF neighbor within the dead interval, the interface considers the neighbor Down. The dead interval must be greater than the interval at which Hello packets are sent, and devices on the same network segment must have the same dead interval.
By default, the dead interval of OSPF neighbor relationships is four times the interval at which Hello packets are sent.Prerequisites
Run the ospf enable multi-area command first.
Precautions
The ospf timer dead multi-area command does not apply to null interfaces.
