module: ios_evpn_evi
short_description: Resource module to configure L2VPN EVPN EVI.
description: This module provides declarative management of L2VPN EVPN EVI on Cisco IOS network
  devices.
version_added: 5.3.0
author: Padmini Priyadarshini Sivaraj (@PadminiSivaraj)
notes:
  - Tested against Cisco IOS-XE device with Version 17.13.01 on Cat9k on CML.
  - This module works with connection C(network_cli).
    See U(https://docs.ansible.com/ansible/latest/network/user_guide/platform_ios.html)
