Enabling OSPFv3 on an Interface

Enabling OSPFv3 on an Interface


After enabling OSPFv3 in the system view, you need to enable OSPFv3 on the interface.

Because an interface has multiple instances, you need to specify which instance of the interface is enabled in the OSPFv3 process when OSPFv3 is enabled on the interface. If no instance ID is specified, the value defaults to 0. The same instance must be enabled on the interfaces between which the neighbor relationship is set up.

Do as follows on the switch that runs OSPFv3.


  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

    The interface view is displayed.

  3. On an Ethernet interface, run undo portswitch

    The interface is switched to Layer 3 mode.

    By default, an Ethernet interface works in Layer 2 mode.

    The mode switching function takes effect when the interface only has attribute configurations (for example, shutdown and description configurations). Alternatively, if configuration information supported by both Layer 2 and Layer 3 interfaces exists (for example, mode lacp and lacp system-id configurations), no configuration that is not supported after the working mode of the interface is switched can exist. If unsupported configurations exist on the interface, delete the configurations first and then run the undo portswitch command.


    If many Ethernet interfaces need to be switched to Layer 3 mode, run the undo portswitch batch interface-type { interface-number1 [ to interface-number2 ] } &<1-10> command in the system view to switch these interfaces to Layer 3 mode in batches.

  4. Run ospfv3 process-id area area-id [ instance instance-id ]

    OSPFv3 is enabled on the interface.

    The area ID can be a decimal integer or in the IPv4 address format, but it is displayed in the IPv4 address format.

  5. (Optional) Run the ospfv3 network-type { broadcast | nbma | p2mp [ non-broadcast ] | p2p } [ instance instance-id ] command to configure the network type of an interface.


    When an interface supports multi-instances, you must specify the value of instance-id when enabling OSPFv3 on the interface. If the value of instance-id is not specified, the default value 0 is adopted. In this case, the configured network type of an interface mismatches the actual network type of the interface. This step is mandatory in such a case.

  6. Run commit

    The configuration is committed.
