Another question: Last time I rebooted the Overcloud, and the 169.254.169.254 route was gone, is this normal ? It is supposed that for every reboot 169.254.169.254 route exists, right ? Maybe its OS image issue or something else ?</span>

DHCP allows pushing static routes via option 21. So we push said route<br>
via DHCP. This is a built-in feature of Neutron.<br>
