2. Prerequisites

Basic knowledge of Ansible
Familiarity with Juniper devices and Junos OS
Ansible installed on your machine
SSH access to Juniper devices

3. Ansible Setup

To get started with Ansible, you need to install it and set up your inventory file.

3.1. Install Ansible

sudo apt-get update

4. Juniper Automation

Use Ansible to automate tasks on Juniper devices, such as configuration and software upgrades.

4.1. Sample Playbook

Here’s a basic playbook example to configure a static route:

- hosts: juniper
  gather_facts: no
  tasks:
    - name: Configure static route
      juniper_junos_config:
        lines:
          - set routing-options static route 10.0.0.0/24 next-hop 192.168.1.254
        commit: true

4.2. Running the Playbook

To execute your playbook, use the following command:

ansible-playbook -i hosts playbook.yml

5. Best Practices

Always test your playbooks in a lab environment before production.
Use version control (e.g., Git) for your Ansible playbooks.
Implement error handling in your playbooks.
Document your Ansible playbooks for better maintainability.
