+--- Tenant Networking Considerations ---
+
+By default, tenant_network_types in ml2_conf.ini only has one item 'vxlan'.
+In order to support other types of network (such as vlan), create a file
+'/etc/kolla/config/neutron/ml2_conf.ini' on the jump server with content:
+
+ [ml2]
+ tenant_network_types = vxlan,vlan
+
+ [ml2_type_vlan]
+ network_vlan_ranges = physnet1:1100:1110
+
+
+The operator can make these changes even after services were already deployed
+by using following command:
+
+ kolla-ansible reconfigure
+
+Then, if it helps, create a temporary network just to make sure:
+
+[root@tanabata kolla]# neutron net-create demo-net2 --provider:network_type vlan
+Created a new network:
