 """Set VCS Virtual IP. Args: vip (str):
 IPv4/IPv6 Virtual IP Address. rbridge_id (str):
 rbridge-id for device. Only required when type is `ve`. delete (bool):
 Deletes the virtual ip if `delete` is ``True``. get (bool):
 Get config instead of editing config. (True, False) callback (function):
 A function executed upon completion of the method. The only parameter passed to `callback` will be the ``ElementTree`` `config`. Returns: Return value of `callback`. Raises: KeyError: if `vip` is not passed. ValueError: if `vip` is invalid. Examples: """
