.. _interfaces-modes:
Interface Modes
===============
The optional ``mode`` option is available on all interfaces, and allows
selecting the high-level behaviour of the interface from a number of modes.
These modes affect how Reticulum selects paths in the network, how announces
are propagated and how long paths are valid.
Configuring modes on interfaces is not strictly necessary, but can be useful
when building or connecting to more complex networks. When not running a
Transport Node, it is rarely useful to configure an interface mode.
* | The default value is ``full``. In this mode, all discovery,
meshing and transport functionality is activated.
* | In the ``access_point`` (or shorthand ``ap``) mode, the
interface will operate as a network access point. In this
mode, announces will not be automatically broadcasted on
the interface, and paths to destinations on the interface
will have a much shorter expiry time. This mode is useful
for creating interfaces that are mostly quiet, unless when
someone is actually using them. An example of this could
be a radio interface serving a wide area, where users are
expected to connect momentarily, use the network, and then
disappear again.
* | The ``roaming`` mode should be used on interfaces that are
roaming (physically mobile), seen from the perspective of
other nodes in the network. As an example, if a vehicle is
equipped with an external LoRa interface, and an internal,
WiFi-based interface, that serves devices that are moving
_with_ the vehicle, the external LoRa interface should be
configured as ``roaming``, and the internal interface can
be left in the default mode. With transport enabled, such
a setup will allow all internal devices to reach each other,
and all other devices that are available on the LoRa side
of the network, when they are in range. Devices on the LoRa
side of the network will also be able to reach devices
internal to the vehicle, when it is in range. Paths via
``roaming`` interfaces also expire faster.
* | The purpose of the ``boundary`` mode is to specify interfaces
that establish connectivity with network segments that are
significantly different than the one this node exists on.
As an example, if a Reticulum instance is part of a LoRa-based
network, but also has a high-speed connection to a
public Transport Node available on the Internet, the interface
connecting over the Internet should be set to ``boundary`` mode.
For a table describing the impact of all modes on announce propagation,
please see the :ref:`Announce Propagation Rules<understanding-announcepropagation>` section.

Announce Propagation Rules
--------------------------
The following table illustrates the rules for automatically propagating announces
from one interface type to another, for all possible combinations. See the
:ref:`Interface Modes<interfaces-modes>` section for a conceptual overview of the
different interface modes, and how they are configured.

.. _interfaces-modes:
Interface Modes
===============
The optional ``mode`` option is available on all interfaces, and allows
selecting the high-level behaviour of the interface from a number of modes.
These modes affect how Reticulum selects paths in the network, how announces
are propagated and how long paths are valid.
Configuring modes on interfaces is not strictly necessary, but can be useful
when building or connecting to more complex networks. When not running a
Transport Node, it is rarely useful to configure an interface mode.
* | The default value is ``full``. In this mode, all discovery,
meshing and transport functionality is activated.
* | In the ``access_point`` (or shorthand ``ap``) mode, the
interface will operate as a network access point. In this
mode, announces will not be automatically broadcasted on
the interface, and paths to destinations on the interface
will have a much shorter expiry time. This mode is useful
for creating interfaces that are mostly quiet, unless when
someone is actually using them. An example of this could
be a radio interface serving a wide area, where users are
expected to connect momentarily, use the network, and then
disappear again.
* | The ``roaming`` mode should be used on interfaces that are
roaming (physically mobile), seen from the perspective of
other nodes in the network. As an example, if a vehicle is
equipped with an external LoRa interface, and an internal,
WiFi-based interface, that serves devices that are moving
_with_ the vehicle, the external LoRa interface should be
configured as ``roaming``, and the internal interface can
be left in the default mode. With transport enabled, such
a setup will allow all internal devices to reach each other,
and all other devices that are available on the LoRa side
of the network, when they are in range. Devices on the LoRa
side of the network will also be able to reach devices
internal to the vehicle, when it is in range. Paths via
``roaming`` interfaces also expire faster.
* | The purpose of the ``boundary`` mode is to specify interfaces
that establish connectivity with network segments that are
significantly different than the one this node exists on.
As an example, if a Reticulum instance is part of a LoRa-based
network, but also has a high-speed connection to a
public Transport Node available on the Internet, the interface
connecting over the Internet should be set to ``boundary`` mode.
For a table describing the impact of all modes on announce propagation,
please see the :ref:`Announce Propagation Rules<understanding-announcepropagation>` section.
