Brocade FastIron Ethernet Switch Layer 3 Routing Configuration Guide - Manual (Page 292)

Syntax: [no] graceful-restart restart-time seconds
The seconds variable sets the maximum restart wait time advertised to neighbors.
Possible values are 10 - 1800 seconds.
The default value is 120 seconds.
Disabling OSPF Graceful Restart helper mode for the global instance
By default, a router supports other restarting routers as a helper. You can prevent your router from
participating in OSPF Graceful Restart by using the following command.
device(config) router ospf
device(config-ospf-router)# graceful-restart helper-disable
Syntax: [no] graceful-restart helper-disable
This command disables OSPF Graceful Restart helper mode.
The default behavior is to help the restarting neighbors.
Configuring OSPF Graceful Restart per VRF
The following sections describe how to enable the OSPF Graceful Restart feature on a specified VRF.
Use the following command to enable the graceful restart feature on a specified VRF.
device(config)# router ospf vrf blue
device(config-ospf-router)# graceful-restart
Syntax: [no] graceful-restart
NOTE
By default, graceful restart is enabled.
Configuring OSPF Graceful Restart time per VRF
Use the following command to specify the maximum amount of time advertised to an OSPF neighbor
router to maintain routes from and forward traffic to a restarting router.
device(config) router ospf vrf blue
device(config-ospf-router)# graceful-restart restart-time 120
Syntax: [no] graceful-restart restart-time seconds
The seconds variable sets the maximum restart wait time advertised to OSPF neighbors of the VRF.
Possible values are 10 - 1200 seconds.
The default value is 60 seconds.
Disabling OSPF Graceful Restart helper mode per VRF
You can prevent your router from participating in OSPF Graceful Restart with VRF neighbors by using
the following command.
device(config) router ospf vrf blue
device(config-ospf-router)# graceful-restart helper-disable
