ospfv3 timer dead

ospfv3 timer dead

Function

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.

Format

ospfv3 timer dead interval [ instance instance-id ]

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

Parameters

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.

Views

Default Level

2: Configuration level

Usage Guidelines

Usage Scenario

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.

Prerequisites

Before running this command on an interface, run the ospfv3 area command on the interface to enable OSPFv3.

Precautions

The command cannot be run on a null interface.

If the dead interval of an OSPFv3 neighbor is shorter than 10s, the session may be closed. Therefore, if dead interval is shorter than 10s, the actual dead interval of an OSPFv3 neighbor is not shorter than 10s. If the conservative mode is configured using the ospfv3 timer hello command, the configured dead timer takes effect even when its value is less than 10s.

To speed up OSPFv3 convergence in the case of a link failure, Configuring BFD for OSPFv3 is recommended.

Example

# Set the dead interval of the neighbor to 80 seconds for VLANIF10.

<HUAWEI> system-view
[~HUAWEI] ospfv3
[*HUAWEI-ospfv3-1] router-id 10.1.1.1
[*HUAWEI-ospfv3-1] quit
[*HUAWEI] interface vlanif 10
[*HUAWEI-Vlanif10] ipv6 enable
[*HUAWEI-Vlanif10] ospfv3 1 area 1
[*HUAWEI-Vlanif10] ospfv3 timer dead 80

# Set the dead interval of the neighbor to 80 seconds for 10GE1/0/1.

<HUAWEI> system-view
[~HUAWEI] ospfv3
[*HUAWEI-ospfv3-1] router-id 10.1.1.1
[*HUAWEI-ospfv3-1] quit
[*HUAWEI] interface 10ge 1/0/1
[*HUAWEI-10GE1/0/1] undo portswitch
[*HUAWEI-10GE1/0/1] ipv6 enable
[*HUAWEI-10GE1/0/1] ospfv3 1 area 1
[*HUAWEI-10GE1/0/1] ospfv3 timer dead 80
