module: iosxr_vrf_global
short_description: Manages global VRF configuration.
description:
  - This module manages VRF configurations on Cisco IOS-XR devices.
  - It enables playbooks to handle either individual VRFs or the complete VRF collection.
  - It also permits removing non-explicitly stated VRF definitions from the setup.
version_added: 9.0.0
author: Ruchi Pakhle (@Ruchip16)
notes:
  - Tested against Cisco IOS-XR Version 9.0.0
  - This module works with connection C(network_cli).
  - See L(the IOS_XR Platform Options, https://github.com/ansible-collections/cisco.iosxr/blob/main/platform_guide.rst).
  - The module examples uses callback plugin (stdout_callback = yaml) to generate task output in yaml format.

    description:
      - This option is used only with state I(parsed).
      - The value of this option should be the output received from the IOS-XR device by
        executing the command B(show running-config vrf).
      - The state I(parsed) reads the configuration from C(running_config) option and
        transforms it into Ansible structured data as per the resource module's argspec
        and the value is then returned in the I(parsed) key within the result.
    type: str
  state:
    choices: [parsed, gathered, deleted, merged, replaced, rendered, overridden, purged]
    default: merged
    description:
      - The state the configuration should be left in
      - The states I(rendered), I(gathered) and I(parsed) does not perform any change
        on the device.
      - The state I(rendered) will transform the configuration in C(config) option to
        platform specific CLI commands which will be returned in the I(rendered) key
        within the result. For state I(rendered) active connection to remote host is
        not required.
      - The state I(gathered) will fetch the running configuration from device and transform
        it into structured data in the format as per the resource module argspec and
        the value is returned in the I(gathered) key within the result.
      - The state I(parsed) reads the configuration from C(running_config) option and
        transforms it into JSON format as per the resource module parameters and the
        value is returned in the I(parsed) key within the result. The value of C(running_config)
        option should be the same format as the output of command I(show running-config vrf).
        connection to remote host is not required.
      - The state I(purged) removes all the VRF configurations from the
        target device. Use caution with this state.
      - The state I(deleted) only removes the VRF attributes that this module
        manages and does not negate the VRF completely. Thereby, preserving
        address-family related configurations under VRF context.
      - Refer to examples for more details.
