Parameters

global: Enables global GR. In global GR mode, a GR process can be completed only when all GR helpers exist. A GR process fails if a GR helper fails (for example, the interface connected to the GR helper goes down). If you do not specify this keyword, the command enables partial GR. In partial GR mode, a GR process can be completed as long as one GR helper exists.

planned-only: Enables planned GR only. If you do not specify this keyword, the command enables both planned GR and unplanned GR.

Usage guidelines

GR includes planned GR and unplanned GR.

OSPFv3 GR and OSPFv3 NSR are mutually exclusive. Do not configure the graceful-restart enable command and the non-stop-routing command at the same time.

To prevent service interruption after a master/backup switchover, a GR restarter running OSPFv3 must perform the following tasks:

Examples

# Enable the GR capability for OSPFv3 process 1.

<Sysname> system-view
[Sysname] ospfv3 1
[Sysname-ospfv3-1] graceful-restart enable
