GRACEFUL-RESTART
bgp graceful-restart
Overview Use this command to enable BGP and BGP4+ graceful-restart capabilities for
restart and stalepath times.
Use the no variant of this command to restore restart timers to their default
settings.
Syntax
bgp graceful-restart [restart-time <delay-value>|
stalepath-time <delay-value>]
no bgp graceful-restart [restart-time|stalepath-time]
Default Graceful restart is disabled by default. If you enable it and do not specify the
restart-time and stalepath-time, they default to 120 seconds.
Mode Router Configuration
Usage The restart-time parameter is used for setting the maximum time that a
graceful-restart neighbor waits to come back up after a restart. This restart-time
value is applied to neighbors unless you explicitly override it by configuring the
corresponding value on the neighbor.
The stalepath-time parameter is used to set the maximum time to preserve stale
paths from a gracefully restarted neighbor. All stalepaths, unless reinstated by the
neighbor after a re-establishment, will be deleted when time, as specified by the
stalepath-time parameter, expires.
Examples To enable graceful restart, use the commands:
awplus# configure terminal
awplus(config)# router bgp 10
awplus(config-router)# bgp graceful-restart
To disable graceful restart, use the commands:
awplus# configure terminal
awplus(config)# router bgp 10
awplus(config-router)# no bgp graceful-restart
