.. _node.network.routed_bridge.addr:

:kw:`addr`
==========

================= ================================================================
**scopable**      True
**required**      False
**default**       Detect using a name resolution of <nodename>. Beware, if the nodename resolves to 127.0.1.1 or 127.0.0.1 the ipip tunnel can not work.
**scope order**   specific > generic
================= ================================================================

The ip address used as local endpoint for the ipip tunnel configured by network setup to access the backend subnet of peer nodes not on the same subnet.

.. _node.network.routed_bridge.ips_per_node:

:kw:`ips_per_node`
==================

================= ================================================================
**scopable**      False
**required**      False
**default**       1024
**scope order**   specific > generic
**convert**       integer
================= ================================================================

The number of allocatable ips per node on the network. Converted to the closest power of two.

.. _node.network.routed_bridge.network:

:kw:`network`
=============

================= ================================================================
**scopable**      False
**required**      False
**default**       10.22.0.0/16
**scope order**   specific > generic
================= ================================================================

The cluster backend network. The routed_bridge driver fragments this network into :kw:`ips_per_nodes` blocks subnets.

.. _node.network.routed_bridge.subnet:

:kw:`subnet`
============

================= ================================================================
**scopable**      True
**required**      False
**default**       None
**scope order**   specific > generic
================= ================================================================

The cidr subnet handled by this node. This parameter must be scoped for each node. Usually, the subnets are allocated automatically upon initial network setup, each node being attributed a subnet based on its index in the cluster.nodes list.

.. _node.network.routed_bridge.tables:

:kw:`tables`
============

================= ================================================================
**scopable**      False
**required**      False
**default**       main
**scope order**   specific > generic
**convert**       list
================= ================================================================

The list of routing tables to add the backend network routes to. The list of available tables is in ``/etc/iproute2/rt_tables``.

.. _node.network.routed_bridge.tunnel:

:kw:`tunnel`
============

================= ================================================================
**scopable**      False
**required**      False
**default**       auto
**scope order**   specific > generic
**candidates**    auto | always
================= ================================================================

Create and route trafic through tunnels to peer nodes policy. ``auto`` tunnel if the peer is not in the same subnet, ``always`` tunnel even if the peer seems to be in the same subnet (some hosting providers require this as traffic goes through router even between adjacent nodes.
