+Chained Replication
+~~~~~~~~~~~~~~~~~~~
+
+.. versionadded:: 2.0
+
+Chained replication occurs when a :term:`secondary` member replicates
+from another secondary member instead of from the :term:`primary`. This
+might be the case, for example, if a secondary selects its replication
+target based on ping time and if the closest member is another secondary.
+
+Chained replication can reduce load on the primary. But chained
+replication can also result in increased replication lag, depending on
+the topology of the network.
+
+Beginning with version 2.2.2, you can use the
+:data:`chainingAllowed <local.system.replset.settings.chainingAllowed>`
+setting in
+:doc:`/reference/replica-configuration` to disable chained replication
+for situations where chained replication is causing lag. For details, see
+:ref:`replica-set-config-chained-replication`.

+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

+:ref:`replica-set-chained-replication` is enabled by default. This
+procedure describes how to disable it and how to re-enable it.
+
+To disable chained replication, set the
+:data:`local.system.replset.settings.chainingAllowed`
+field in :doc:`/reference/replica-configuration` to ``false``.
+
+You can use the following sequence of commands to set ``chainingAllowed`` to
+``false``:
+
+1. Copy the configuration settings into the ``cfg`` object:
+
+   .. code-block:: javascript
+
+      cfg = rs.config()
+
+#. Take note of whether the current configuration settings contain the
+   ``settings`` sub-document. If they do, skip this step.
+
+   .. warning:: To avoid data loss, skip this step if the configuration
+      settings contain the ``settings`` sub-document.
+
+   If the current configuration settings **do not** contain the
+   ``settings`` sub-document, create the sub-document by issuing the
+   following command:
+
+   .. code-block:: javascript
+
+      cfg.settings = { }
+
+#. Issue the following sequence of commands to set ``chainingAllowed``
+   to ``false``:
+
+   .. code-block:: javascript
+
+      cfg.settings.chainingAllowed = false
+      rs.reconfig(cfg)
+
+To re-enable chained replication, set ``chainingAllowed`` to ``true``.
+You can use the following sequence of commands:
+
+.. code-block:: javascript
+
+   cfg = rs.config()
+   cfg.settings.chainingAllowed = true
+   rs.reconfig(cfg)
+
+.. note:: If chained replication is disabled, you still can use
+   :dbcommand:`replSetSyncFrom` to specify that a secondary replicates
+   from another secondary. But that configuration will last only until the
+   secondary recalculates which member to sync from.
