dcn ospf enable (interface view)

Function

The dcn ospf enable command enables the Open Shortest Path First (OSPF) function on the DCN interface.

The undo dcn ospf enable command disables the OSPF function on the DCN interface.

By default, the OSPF function is disabled on DCN interfaces.

Format

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

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

Usage Guidelines

Usage Scenario

To enable OSPF on DCN serial interfaces or sub-interfaces 4094 in a specified process and area, run the dcn ospf enable command.

Prerequisites

DCN has been enabled using the dcn command in the interface view, or DCN communication through sub-interfaces 4094 has been enabled using the dcn mode vlan command in the GE interface view.

Precautions

If multiple DCN interfaces of an interface share one IP address, do not use the network command to enable the OSPF function on the DCN interfaces.

The dcn ospf enable command cannot work with the network command. If both of the commands are run on an interface, the interface status may become unstable.

In VS mode, this command is supported only by the admin VS.

Example

# Enable the OSPF function in process 100 and area 1 of GE 0/1/0.
