Configuring BGP4 Restart for a VRF
Use the following command to enable the BGP4 Restart feature for a specified VRF.
device(config)# router bgp
device(config-bgp-router)# address-family ipv4 unicast vrf blue
device(config-bgp-ipv4u-vrf)# graceful-restart
Syntax: [no] graceful-restart
Configuring timers for BGP4 Restart (optional)
You can optionally configure the following timers to change their values from the default values:
• Restart Timer
• Stale Routes Timer
• Purge Timer
The seconds variable sets the maximum restart wait time advertised to neighbors. Possible values are
1- 3600 seconds. The default value is 120 seconds.
Configuring the restart timer for BGP4 Restart
Use the following command to specify the maximum amount of time a device will maintain routes from
and forward traffic to a restarting device.
device(config-bgp)# graceful-restart restart-time 150
Syntax: [no] graceful-restart restart-time seconds
The seconds variable sets the maximum restart wait time advertised to neighbors. Possible values are
1 through 3600 seconds. The default value is 120 seconds.
Configuring BGP4 Restart stale routes timer
Use the following command to specify the maximum amount of time a helper device will wait for an
end-of-RIB message from a peer before deleting routes from that peer.
device(config-bgp)# graceful-restart stale-routes-time 120
Syntax: [no] graceful-restart stale-routes-time seconds
The seconds variable sets the maximum time before a helper device cleans up stale routes. Possible
values are 1 through 3600 seconds. The default value is 360 seconds.
Configuring BGP4 Restart purge timer
Use the following command to specify the maximum amount of time a device will maintain stale routes
in its routing table before purging them.
device(config-bgp)# graceful-restart purge-time 900
Syntax: [no] graceful-restart purge-time seconds
The seconds variable sets the maximum time before a restarting device cleans up stale routes.
Possible values are 1 - 3600 seconds. The default value is 600 seconds.
