The default is 120 seconds.
• Set maximum time to retain the restarting peer’s stale paths.
CONFIG-ROUTER-BGP mode
bgp graceful-restart [stale-path-time time-in-seconds]
The default is 360 seconds.
• Local router supports graceful restart as a receiver only.
CONFIG-ROUTER-BGP mode
bgp graceful-restart [role receiver-only]
Enabling Neighbor Graceful 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.
With the graceful restart feature, Dell Networking OS enables the receiving/restarting mode by default. In Receiver-Only mode, graceful
restart saves the advertised routes of peers that support this capability when they restart. This option provides support for remote peers
for their graceful restart without supporting the feature itself.
You can implement BGP graceful restart either by neighbor or by BGP peer-group. For more information, refer to the Dell Networking OS
Command Line Interface Reference Guide.
• Add graceful restart to a BGP neighbor or peer-group.
CONFIG-ROUTER-BGP mode
neighbor {ip-address | peer-group-name} graceful-restart
• Set the maximum restart time for the neighbor or peer-group.
CONFIG-ROUTER-BGP mode
neighbor {ip-address | peer-group-name} graceful-restart [restart-time time-in-seconds]
The default is 120 seconds.
• Local router supports graceful restart for this neighbor or peer-group as a receiver only.
CONFIG-ROUTER-BGP mode
neighbor {ip-address | peer-group-name} graceful-restart [role receiver-only]
• Set the maximum time to retain the restarting neighbor’s or peer-group’s stale paths.
CONFIG-ROUTER-BGP mode
neighbor {ip-address | peer-group-name} graceful-restart [stale-path-time time-in-seconds]
The default is 360 seconds.
Enabling or disabling BGP neighbors
You can enable or disable all the congured BGP neighbors using the shutdown all command in ROUTER BGP mode.
To disable all the congured BGP neighbors:
1 Enter the router bgp mode using the following command:
CONFIGURATION Mode
router bgp as-number
