Note that this option will persist after saving the configuration during
runtime, unless unset by the ``no bgp no-rib`` command in VTY shell prior to
a configuration write operation.

To set and unset the BGP daemon ``-n`` / ``--no_kernel`` options during runtime
to disable BGP route installation to the RIB (Zebra), the ``[no] bgp no-rib``
commands can be used;
Please note that setting the option during runtime will withdraw all routes in
the daemons RIB from Zebra and unsetting it will announce all routes in the
daemons RIB to Zebra. If the option is passed as a command line argument when

unless removed from the configuration with the negating command prior to the
configuration write operation.
