Upon receiving the Grace-LSA, the neighbors with the GR helper capability enter the helper mode (and
are called "GR helpers"). Then, the GR restarter retrieves its adjacencies and LSDB with the help of the
GR helpers.
Examples
# Enable the GR helper capability for OSPFv3 process 1.
<Sysname> system-view
[Sysname] ospfv3 1
[Sysname-ospfv3-1] graceful-restart helper enable
Related commands
