Enabling OSPFv3 on an Interface

Context

After enabling OSPFv3 in the system view, enable OSPFv3 on an interface.

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

Perform the following operations on the switch that runs OSPFv3.

Procedure

Run system-view
The system view is displayed.
Run interface interface-type interface-number
The interface view is displayed.
(Optional) 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.

Only the S5720-EI, S5720-HI, S5730-HI, S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S6720-EI, S6720-HI, S6720S-EI, S6730-H, S6730S-H, S6730-S, and S6730S-S support switching between Layer 2 and Layer 3 modes.
Run ospfv3 process-id area area-id [ instance instance-id ]
OSPFv3 is enabled on the interface.

The area ID can be entered as a decimal integer or in the IPv4 address format, but it is always displayed in the IPv4 address format.
(Optional) Run the ospfv3 network-type { broadcast | nbma | p2mp [ non-broadcast ] | p2p } [ instance instance-id ] command to configure a network type for the 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 used. In this case, the configured network type of an interface may not match the actual network type of the interface. This step is mandatory in such a case.
