module: ios_l3_interfaces
short_description: Resource module to configure L3 interfaces.
description:
  - This module provides declarative management of Layer-3 interface on Cisco IOS devices.
version_added: 1.0.0
author:
  - Sagar Paul (@KB-perByte)
  - Sumit Jaiswal (@justjais)
notes:
  - Tested against Cisco IOSXE Version 17.3 on CML.
  - Using deleted state without config will delete all l3 attributes from all the interfaces.
  - This module works with connection C(network_cli).
    See U(https://docs.ansible.com/ansible/latest/network/user_guide/platform_ios.html)
  - The module examples uses callback plugin (stdout_callback = yaml) to generate task
    output in yaml format.

      - 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 | section ^interface) executed on device. For state I(parsed) active
        connection to remote host is not required.
