The `Cisco IOS-XR collection <https://galaxy.ansible.com/ui/repo/published/cisco/iosxr>`_ supports multiple connections. This page offers details on how each connection works in Ansible and how to use it.

The ``ansible_connection: local`` has been deprecated. Please use ``ansible_connection: ansible.netcommon.network_cli`` or ``ansible_connection: ansible.netcommon.netconf`` instead.

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

Example CLI inventory ``[iosxr:vars]``
--------------------------------------

.. code-block:: ini

   [iosxr:vars]
   ansible_connection=ansible.netcommon.network_cli
   ansible_network_os=cisco.iosxr.iosxr
   ansible_user=myuser
   ansible_password=!vault...
   ansible_paramiko_proxy_command='-o ProxyCommand="ssh -W %h:%p -q bastion01"'


- 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_paramiko_proxy_command`` 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: Retrieve IOS-XR version
     cisco.iosxr.iosxr_command:
       commands: show version
     when: ansible_network_os == 'cisco.iosxr.iosxr'


Using NETCONF in Ansible
========================

Enabling NETCONF
----------------

Before you can use NETCONF to connect to a switch, you must:

- install the ``ncclient`` python package on your control node(s) with ``pip install ncclient``
- enable NETCONF on the Cisco IOS-XR device(s)

To enable NETCONF on a new switch with Ansible, use the ``cisco.iosxr.iosxr_netconf`` module through the CLI connection. Set up your platform-level variables just like in the CLI example above, then run a playbook task like this:

.. code-block:: yaml

   - name: Enable NETCONF
     connection: ansible.netcommon.network_cli
     cisco.iosxr.iosxr_netconf:
     when: ansible_network_os == 'cisco.iosxr.iosxr'

Once NETCONF is enabled, change your variables to use the NETCONF connection.

Example NETCONF inventory ``[iosxr:vars]``
------------------------------------------

.. code-block:: ini

   [iosxr:vars]
   ansible_connection=ansible.netcommon.netconf
   ansible_network_os=cisco.iosxr.iosxr
   ansible_user=myuser
   ansible_password=!vault |
   ansible_paramiko_proxy_command='-o ProxyCommand="ssh -W %h:%p -q bastion01"'


Example NETCONF task
--------------------

.. code-block:: yaml

   - name: Configure hostname and domain-name
     cisco.iosxr.iosxr_system:
       hostname: iosxr01
       domain_name: test.example.com
       domain_search:
         - ansible.com
         - redhat.com
         - cisco.com
