JunOS Switch
============

This role configures Juniper switches using the `junos` Ansible modules.  It
provides a fairly minimal abstraction of the configuration interface provided
by the `junos` modules, allowing for application of arbitrary switch
configuration options.

Requirements
------------

The switches should be configured to allow access to NETCONF via SSH.

Role Variables
--------------

`junos_switch_delegate_to` is the host on which to execute the `junos` Ansible
modules.

`junos_switch_provider` is authentication provider information passed as the
`provider` argument to the `junos` modules.

`junos_switch_config_format` is the format of configuration in
`junos_switch_config` and `junos_switch_interface_config`. May be one of `set`,
`text` or `json`.

`junos_switch_config` is a list of configuration lines to apply to the switch,
and defaults to an empty list.

`junos_switch_interface_config` contains interface configuration. It is a dict
mapping switch interface names to configuration dicts. Each dict may contain
the following items:

- `description` - a description to apply to the interface.
- `config` - a list of per-interface configuration.

Dependencies
------------

None

Example Playbook
----------------

The following playbook configures hosts in the `junos-switches` group.
It assumes host variables for each switch holding the host, username and
passwords.  It applies global configuration for LLDP, and enables two
10G ethernet interfaces.
