The `FRR <https://galaxy.ansible.com/frr/frr>`_ collection supports the ``ansible.netcommon.network_cli`` connection. This section provides details on how to use this connection for Free Range Routing (FRR).

Using CLI in Ansible
====================

Example CLI ``group_vars/frr.yml``
----------------------------------

.. code-block:: yaml

   ansible_connection: ansible.netcommon.network_cli
   ansible_network_os: frr.frr.frr
   ansible_user: frruser
   ansible_password: !vault...
   ansible_ssh_common_args: '-o ProxyCommand="ssh -W %h:%p -q bastion01"'

- The ``ansible_user`` should be a part of the ``frrvty`` group and should have the default shell set to ``/bin/vtysh``.
- If you are using SSH keys (including an ssh-agent) you can remove the ``ansible_password`` configuration.
- If you are accessing your host directly (not through a bastion/jump host) you can remove the ``ansible_ssh_common_args`` configuration.
- If you are accessing your host through a bastion/jump host, you cannot include your SSH password in the ``ProxyCommand`` directive. To prevent secrets from leaking out (for example in ``ps`` output), SSH does not support providing passwords through environment variables.

Example CLI task
----------------

.. code-block:: yaml

   - name: Gather FRR facts
     frr.frr.frr_facts:
       gather_subset:
        - config
        - hardware
