| Doc Text: |
This introduces an enhancement that you can configure to prevent flooding on the mesh between instances on different tenant networks.
+
Before this update, RHOSP environments with the OVN or OVS mechanism driver that had DVR enabled and used VLAN tenant networks, east/west traffic between instances connected to different tenant networks was flooded to the fabric.
+
To prevent this flooding in environments that use the OVN mechanism driver, you now can configure the parameter `OVNControllerGarpMaxTimeout` to control the frequency at which ovn-controller sends out out gratuitous ARP packets that announce MAC addresses of ports on VLAN tenant networks.
+
This parameter is not available in environments that use the OVS mechanism driver.
