# To set the pod network CIDR range, uncomment the following property and set its value:
#
# openshift_openstack_kuryr_pod_subnet_prefixlen: 24
#
# The subnet prefix length value must be smaller than the CIDR value that is
# set in the inventory file as openshift_openstack_kuryr_pod_subnet_cidr.
# By default, this value is /24.

# openshift_portal_net is the range that OpenShift services and their associated Octavia
# load balancer VIPs use. Amphora VMs use Neutron ports in the range that is defined by
# openshift_openstack_kuryr_service_pool_start and openshift_openstack_kuryr_service_pool_end.
#
# The value of openshift_portal_net in the OSEv3.yml file must be within the range that is
# defined by openshift_openstack_kuryr_service_subnet_cidr. This range must be half
# of openshift_openstack_kuryr_service_subnet_cidr's range. This practice ensures that
# openshift_portal_net does not overlap with the range that load balancers' VMs use, which is
# defined by openshift_openstack_kuryr_service_pool_start and openshift_openstack_kuryr_service_pool_end.
#
