 Example 2: simplifying playbooks with network agnostic modules

 If you have two or more network platforms in your environment, you can use the network agnostic modules to simplify your playbooks. You can use network agnostic modules such as ``cli_command`` or ``cli_config`` in place of the platform-specific modules such as ``eos_config``, ``ios_config``, and ``junos_config``. This reduces the number of tasks and conditionals you need in your playbooks.
