  2. Run bgp { as-number-plain | as-number-dot }

    The BGP view is displayed.

  3. Run graceful-restart

    BGP GR is enabled.

    By default, BGP GR is disabled.

  4. (Optional) Run graceful-restart timer wait-for-rib timer

    The time during which the restarting speaker and receiving speaker wait for End-of-RIB messages is set.

    By default, the time for waiting for End-of-RIB messages is 600 seconds.

  5. (Optional) Run graceful-restart peer-reset

    The device is enabled to reset a BGP session in GR mode.

    By default, a device is disabled from resetting a BGP connection in GR mode.
