Configures the router as a graceful BGP restart router.
| none | Do not act as a graceful BGP restart router. |
| planned | Only act as a graceful BGP restart router for planned restarts. |
| unplanned | Only act as a graceful BGP restart router for unplanned restarts. |
| both | Act as a graceful BGP restart router for both planned and unplanned restarts. |
| aware-only | Only act as a graceful BGP receiver (helper) router. |
The default is none; graceful restart is disabled.
This command configures the router as a graceful BGP router. You can decide to configure a router to enter graceful restart for only planned restarts, for only unplanned restarts, or for both. Also, you can decide to configure a router to be a receiver only (which helps a restarting BGP router to perform the graceful restart process), and not to do graceful restarts itself.
After a graceful restart, the switch preserves the time stamps for all BGP routes in the RIB that were received before the stale timer expired. After restart, the capabilities for all BGP peers are renegotiated.
Note
End of Restart (EOR) messages are not sent to BGP peers if the graceful restart feature is disabled.
This command cannot be used while BGP is enabled globally on the switch.
The following command configures a router to perform graceful BGP restarts only for planned restarts:
configure bgp restart planned
This command was first available in ExtremeXOS 11.4.
This command is available on platforms that support the appropriate license. For complete information about software licensing, including how to obtain and upgrade your license and which licenses support the BGP feature,see the Switch Engine v33.1.1 Licensing Guide document.
