    - Manages configuration of an OSPF VPN instance on HUAWEI CloudEngine switches.
author: Yang yang (@QijunPan)
notes:
    - This module requires the netconf system service be enabled on the remote device being managed.
    - Recommended connection is C(netconf).
    - This module also works with C(local) connections for legacy playbooks.
