+**********
+OpenFabric
+**********
+
+OpenFabric, specified in :t:`draft-white-openfabric-06.txt`, is a routing
+protocol derived from IS-IS, providing link-state routing with efficient
+flooding for topologies like spine-leaf networks.
+
+FRR implements OpenFabric in a daemon called *fabricd*
+
+.. _configuring-fabricd:
+
+Configuring fabricd
+===================
+
+There are no *fabricd* specific options. Common options can be specified
+(:ref:`common-invocation-options`) to *fabricd*. *fabricd* needs to acquire
+interface information from *zebra* in order to function. Therefore *zebra* must
+be running before invoking *fabricd*. Also, if *zebra* is restarted then *fabricd*
+must be too.
+
+Like other daemons, *fabricd* configuration is done in an OpenFabric specific
+configuration file :file:`fabricd.conf`.
+
+.. _openfabric-router:
