- network_interface

  - default_network_interface

  - kolla_external_vip_address

- kolla_external_vip_interface

  - default_kolla_external_vip_interface

For the combined option, set the two variables below, while allowing the

other two to accept their default values.  In this configuration all REST

The "network\_interface" variable is the interface to which Kolla binds API

services. For example, when starting up Mariadb it will bind to the

IP on the interface list in the "network\_interface" variable.

The ``default_network_interface`` variable is the interface to which Kolla

The ``default_neutron_external_interface`` variable is the interface that will

be used for the external bridge in Neutron. Without this bridge the deployment

instance traffic will be unable to access the rest of the Internet. In

the case of a single interface on a machine, a veth pair may be used where

one end of the veth pair is listed here and the other end is in a bridge on

the system.
