.. -*- rst -*- .. needs:method_verification .. needs:parameter_verification .. needs:example_verification .. needs:body_verification ========================================= Layer-3 networking (routers, floatingips) ========================================= Routes packets between subnets, forwards packets from internal networks to external ones, and accesses instances from external networks through floating IPs. This extension introduces these resources: - **router**. A logical entity for forwarding packets across internal subnets and NATting them on external networks through an appropriate external gateway. - **floatingip**. An external IP address that you map to a port in an internal network. List floating IPs ================= .. rest_method:: GET /v2.0/floatingips Lists floating IPs that are accessible to the tenant who submits the request. Default policy settings return only those floating IPs that are owned by the tenant who submits the request, unless an admin user submits the request. This example request lists floating IPs in JSON format: :: GET /v2.0/floatingips Accept: application/json Use the ``fields`` query parameter to control which fields are returned in the response body. Additionally, you can filter results by using query string parameters. For information, see `Filtering and Column Selection `__. Normal response codes: 200 Error response codes: 401 Request ------- Response Parameters ------------------- .. rest_parameters:: parameters.yaml - router_id: router_id - status: status - tenant_id: tenant_id - floating_network_id: floating_network_id - fixed_ip_address: fixed_ip_address - floating_ip_address: floating_ip_address - port_id: port_id - id: id - floatingips: floatingips Response Example ---------------- .. literalinclude:: ../samples/routers/floating-ips-list-response.json :language: javascript Create floating IP ================== .. rest_method:: POST /v2.0/floatingips Creates a floating IP, and, if you specify port information, associates the floating IP with an internal port. To associate the floating IP with an internal port, specify the port UUID attribute in the request body. If you do not specify a port UUID in the request, you can issue a PUT request instead of a POST request. Default policy settings enable only administrative users to set floating IP addresses and some non-administrative users might require a floating IP address. If you do not specify a floating IP address in the request, the operation automatically allocates one. By default, this operation associates the floating IP address with a single fixed IP address that is configured on an OpenStack Networking port. If a port has multiple IP addresses, you must specify the ``fixed_ip_address`` attribute in the request body to associate a fixed IP address with the floating IP address. You can create floating IPs on only external networks. When you create a floating IP, you must specify the UUID of the network on which you want to create the floating IP. Alternatively, you can create a floating IP on a subnet in the external network, based on the costs and quality of that subnet. You must configure an IP address with the internal OpenStack Networking port that is associated with the floating IP address. Error codes: - ``400`` The operation returns this error code for one of these reasons: - The network is not external, such as ``router:external=False``. - The internal OpenStack Networking port is not associated with the floating IP address. - The requested floating IP address does not fall in the subnet range for the external network. - The fixed IP address is not valid. - ``401`` The operation is not authorized. - ``404`` The port UUID is not valid. - ``409`` The operation returns this error code for one of these reasons: - The requested floating IP address is already in use. - The internal OpenStack Networking port and fixed IP address are already associated with another floating IP. Error response codes: 201,404,409,401,400 Request ------- .. rest_parameters:: parameters.yaml - floatingip: floatingip - tenant_id: tenant_id - floating_network_id: floating_network_id - fixed_ip_address: fixed_ip_address - floating_ip_address: floating_ip_address - port_id: port_id Request Example --------------- .. literalinclude:: ../samples/routers/floatingip-create-request.json :language: javascript Response Parameters ------------------- .. rest_parameters:: parameters.yaml - router_id: router_id - status: status - floatingip: floatingip - tenant_id: tenant_id - floating_network_id: floating_network_id - fixed_ip_address: fixed_ip_address - floating_ip_address: floating_ip_address - port_id: port_id - id: id Add interface to router ======================= .. rest_method:: PUT /v2.0/routers/{router_id}/add_router_interface Adds an internal interface to a logical router. Attaches a subnet to an internal router interface. Specify the UUID of a subnet or port in the request body: - Subnet UUID. The gateway IP address for the subnet is used to create the router interface. - Port UUID. The IP address associated with the port is used to create the router interface. When you specify an IPv6 subnet, this operation adds the subnet to an existing internal port with same network UUID, on the router. If a port with the same network UUID does not exist, this operation creates a port on the router for that subnet. The limitation of one IPv4 subnet per router port remains, though a port can contain any number of IPv6 subnets that belong to the same network UUID. When you use the ``port-create`` command to add a port and then call ``router-interface-add`` with this port UUID, this operation adds the port to the router if the following conditions are met: - The port has no more than one IPv4 subnet. The IPv6 subnets, if any, on the port do not have same network UUID as the network UUID of IPv6 subnets on any other ports. If you specify both UUIDs, this operation returns the ``Bad Request (400)`` response code. If the port is already in use, this operation returns the ``Conflict (409)`` response code. This operation returns a port UUID that is either: - The same UUID that is passed in the request body. - The UUID of a port that this operation creates to attach the subnet to the router. After you run this operation, the operation sets: - The device UUID of this port to the router UUID. - The ``device_owner`` attribute to ``network:router_interface``.

This operation deletes an internal router interface, which detaches a subnet from the router. If this subnet UUID is the last subnet on the port, this operation deletes the port itself. You must specify either a subnet UUID or port UUID in the request body; the operation uses this value to identify which router interface to deletes. You can also specify both a subnet UUID and port UUID. If you specify both UUIDs, the subnet UUID must correspond to the subnet UUID of the first IP address on the port. Otherwise, this operation returns the ``Conflict (409)`` response code with information about the affected router and interface. If the router or the subnet and port do not exist or are not visible to you, this operation returns the ``Not Found (404)`` response code. As a consequence of this operation, the operation removes the port connecting the router with the subnet from the subnet for the network.
