module: eos_vrf_global
short_description: Resource module to configure VRF definitions.
description: This module provides declarative management of VRF definitions on Arista EOS platforms.
version_added: 10.0.0
author: Ruchi Pakhle (@Ruchip16)
notes:
- Tested against Arista EOS 4.23.0F
- This module works with connection C(network_cli). See the L(EOS Platform Options,eos_platform_options).
options:
  config:
    description: A list of dictionaries containing device configurations for VRF definitions.
    type: list
    elements: dict
    suboptions:
      name:
        description: Name of the VRF Instance.
        type: str
        required: true
      description:
        description: A description for the VRF.
        type: str
      rd:
        description: BGP Route Distinguisher (RD).
        type: str
  running_config:
    description:
      - This option is used only with state I(parsed).
      - The value of this option should be the output received from the EOS 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.
