Dummy
-----

Dummy interfaces are much like the loopback interface, except you can have
as many as you want. Dummy interfaces can be used as interfaces that always
stay up (in the same fashion to loopbacks in Cisco IOS), or for testing
purposes.

Configuration commands:

.. code-block:: none

  vyos@vyos# set interfaces dummy dum0
  Possible completions:
  +  address      IP address
