# The DHCP server can assist with providing metadata support on isolated
# networks. Setting this value to True will cause the DHCP server to append
# specific host routes to the DHCP request. The metadata service will only
# be activated when the subnet does not contain any router port. The guest
# instance must be configured to request host routes via DHCP (Option 121).

# Allows for serving metadata requests coming from a dedicated metadata
# access network whose cidr is 169.254.169.254/16 (or larger prefix), and
# is connected to a Neutron router from which the VMs send metadata
# request. In this case DHCP Option 121 will not be injected in VMs, as
# they will be able to reach 169.254.169.254 through a router.
