VRF: Graceful Restart

The Tenant service configures graceful restart under each tenant VRF ipv4/v6 unicast address-family.

You can enable graceful restart per tenant VRF during VRF creation and VRF update operations. EFA provisions the user input graceful restart on the switches during the instantiation and update of VRF on the switches.

VRF is instantiated on the switches during a user-triggered L3 EPG create or L2 EPG transition to L3 EPG, based on the endpoints present in the EPG.
VRF is updated on the switches during a user-triggered VRF update operation, based on the endpoints present in the EPGs, using this VRF.

Currently, the enable or disable value of graceful restart depends on the per-user VRF configuration.

Note

By default, graceful restart is disabled. The default value of graceful restart is the switch default.
EFA versions earlier than v2.4 have graceful restart enabled by default.
An upgrade from a version earlier than v2.4 to v2.4 will retain the graceful restart as enabled for all the VRFs that were configured before the upgrade.

EFA Provisioning

When using the efa tenant vrf create command, add the --graceful-restart parameter. For more information, see the efa tenant vrf create command in the Extreme Fabric Automation Command Reference, 2.4.0.
When using the efa tenant vrf update command, add the graceful-restart-update option for the --operation parameter and --graceful-restart parameter. For more information, see the efa tenant vrf update command in the Extreme Fabric Automation Command Reference, 2.4.0.
