Parameters
planned-only
: Enables only planned GR for the GR helper. If you do not specify this keyword, the
command enables both planned GR and unplanned GR for the GR helper. This keyword is available in
Release 2311P04 and later versions.
Usage guidelines
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
