***********************************
Configure Delivery Service Steering
***********************************

#. Create two target :term:`Delivery Services` in Traffic Portal. They must both be HTTP :term:`Delivery Services` that are part of the same CDN.

#. Create a :term:`Delivery Service` with Type ``STEERING`` or ``CLIENT_STEERING`` in Traffic Ops.

#. If desired, a 'steering' :term:`Role` user can create filters for the target :term:`Delivery Services` using :ref:`to-api-steering-id-targets`

	.. note:: This is only available via the :ref:`to-api`; no functionality for manipulating steering targets is offered by Traffic Portal. This feature has been requested and is tracked by `GitHub Issue #2811 <https://github.com/apache/trafficcontrol/issues/2811>`_

#. Any requests to Traffic Router for the steering :term:`Delivery Service` should now be routed to target :term:`Delivery Services` based on configured weight or order.

.. note:: This example assumes that the Traffic Ops instance is running at ``to.cdn.local`` and the administrative username and password are ``admin`` and ``twelve``, respectively. This is *not* recommended in production, but merely meant to replicate the default :ref:`ciab` environment!
