+Trove network isolation
+=======================
+
+.. _network_isolation:
+
+Isolate bussiness network from management network
+-------------------------------------------------
+
+This document aims to help administrator to configure network_isolation in trove.
+
+Before ``Bobcat`` release, trove didn't isolate the management network from bussiness network, sometimes, this
+may cause network performance issue or security issue.
+
+Since ``Bobcat`` release, trove adds a new configure option(network_isolation) to configure network isolation.
+
+network_isolation has the following behaviors and requirements:
+
+* Trove will not check the overlap between management networks cidrs and bussiness networks cidrs anymore.
+  as trove allows the same cidrs between management network and bussiness network.
+
+* Cloud administrator must configure the management_networks in config file. Management network is responsible for
+  connecting with rabbitMQ, as well as docker registry. Even though you have set network_isolation to true, if your
+  management_networks is not configured, Trove will still not plug the network interface into the container.
+
+
+Configure network isolation
+---------------------------
+
+* Setting ``management_networks`` in :file:`/etc/trove/trove.conf`, typically, this is a neutron provider
+  network with a gateway configured. see the :ref:`management network <trove-management-network>`
+
+.. path /etc/trove/trove.conf
+.. code-block:: ini
+
+    [DEFAULT]
+    management_networks = <your-network-id>
+
+* Setting network_isolation to True(default is False)
+
+.. path /etc/trove/trove.conf
+.. code-block:: ini
+
+    [network]
+    network_isolation: True
+
+Upgrade
+-------
+
+This feature is not backward compatible with older Trove guest images; you need to re-build the guest image
+with the updated code. see the :ref:`build image <build_guest_images>`
