router
======

A **router** is a logical component that forwards data packets between
networks. It also provides Layer 3 and NAT forwarding to provide external
network access for servers on project networks.

Network v2

router add port
---------------

Add a port to a router

.. program:: router add port
.. code:: bash

    openstack router add port
        <router>
        <port>

.. _router_add_port:

.. describe:: <router>

    Router to which port will be added (name or ID)

.. describe:: <port>

    Port to be added (name or ID)

router add subnet
-----------------

Add a subnet to a router

.. program:: router add subnet
.. code:: bash

    openstack router add subnet
        <router>
        <subnet>

.. _router_add_subnet:

.. describe:: <router>

    Router to which subnet will be added (name or ID)

.. describe:: <subnet>

    Subnet to be added (name or ID)

router create
-------------

Create new router

.. program:: router create
.. code:: bash

    openstack router create
        [--project <project> [--project-domain <project-domain>]]
        [--enable | --disable]
        [--distributed | --centralized]
        [--ha | --no-ha]
        [--description <description>]
        [--availability-zone-hint <availability-zone>]
        <name>

.. option:: --project <project>

    Owner's project (name or ID)

.. option:: --project-domain <project-domain>

    Domain the project belongs to (name or ID).
    This can be used in case collisions between project names exist.

.. option:: --enable

    Enable router (default)

.. option:: --disable

    Disable router

.. option:: --distributed

    Create a distributed router

    The default router type (distributed vs centralized) is determined by a
    configuration setting in the OpenStack deployment.  Since we are unable
    to know that default wihtout attempting to actually create a router it
    is suggested to use either :option:`--distributed` or :option:`--centralized`
    in situations where multiple cloud deployments may be used.

.. option:: --centralized

    Create a centralized router

    See the note in :option:`--distributed` regarding the default used when
    creating a new router.

.. option:: --ha

    Create a highly available router

.. option:: --no-ha

    Create a legacy router

.. option:: --description <description>

    Set router description

.. option:: --availability-zone-hint <availability-zone>

    Availability Zone in which to create this router
    (Router Availability Zone extension required,
    repeat option to set multiple availability zones)

.. _router_create-name:
.. describe:: <name>

    New router name

router delete
-------------

Delete router(s)

.. program:: router delete
.. code:: bash

    openstack router delete
        <router> [<router> ...]

.. _router_delete-router:
.. describe:: <router>

    Router(s) to delete (name or ID)

router list
-----------

List routers

.. program:: router list
.. code:: bash

    openstack router list
        [--name <name>]
        [--enable | --disable]
        [--long]
        [--project <project> [--project-domain <project-domain>]]

.. option:: --long

    List additional fields in output

.. option:: --name <name>

    List routers according to their name

.. option:: --enable

    List enabled routers

.. option:: --disable

    List disabled routers

.. option:: --project <project>

    List routers according to their project (name or ID)

.. option:: --project-domain <project-domain>

    Domain the project belongs to (name or ID).
    This can be used in case collisions between project names exist.
