ospf enable

Function

The ospf enable command enables OSPF on the interface.

The undo ospf enable command disables OSPF from the interface.

By default, OSPF is not enabled on interfaces.

Format

ospf enable [ process-id ] area { area-id | areaidipv4 }

undo ospf enable [ process-id ] area { area-id | areaidipv4 }

Parameters

Parameter	Description	Value
process-id	Specifies the ID of an OSPF process.	The value is an integer ranging from 1 to 4294967295. The default value is 1.
area area-id	Specifies an area ID in the format of a decimal integer.	The value ranges from 0 to 4294967295 when it is an integer.
areaidipv4	Specifies an area ID in the format of an IP address.	The value is in dotted decimal notation.

Usage Guidelines

Usage Scenario

The ospf enable command configuration takes precedence over the network command configuration.

After the undo ospf enable command is run to disable OSPF from an interface, the network configuration takes effect on the interface automatically.

Configuration Impact

The interface will alternate between Up and Down when the ospf enable and network commands are run on the interface repeatedly.

Precautions

The area specified in the ospf enable command must have been created. Otherwise, the configuration does not take effect.

The configured interface and the OSPF process must be in the same VPN.

The ospf enable command can be configured on an interface before an OSPF process is created. The interface specified in the ospf enable command and the created OSPF process must be in the same VPN.
If a process is created before the ospf enable command is run on an interface, the process of the interface and existing process must belong to the same VPN. Otherwise, the ospf enable command cannot be run.
If no OSPF process is created, interfaces that belong to different VPN instances cannot be added to the same OSPF process.

Example

# Enable GigabitEthernet 0/1/0 in the specified OSPF area.

<HUAWEI> system-view
[~HUAWEI] interface GigabitEthernet0/1/0
[~HUAWEI-GigabitEthernet0/1/0] ospf enable 1 area 0
