Usage
Information
This feature is advertised to BGP neighbors through a capability advertisement. In receiver only mode,
BGP saves the advertised routes of peers that support this capability when they restart.
BGP graceful restart is active only when the neighbor becomes established. Otherwise it is disabled.
Graceful-restart applies to all neighbors with established adjacency.
You cannot enable the graceful restart advertisement capability on a per neighbor basis. You can enable
this global configuration for the whole switch.
This command automatically restarts the BGP instance for the configuration to take effect.
