+    Manually restrict access to the router API. When the API is disabled,
+    all its methods throw a Lua error, except
+    :ref:`vshard.router.cfg() <router_api-cfg>`,
+    :ref:`vshard.router.new() <router_api-new>`,
+    :ref:`vshard.router.enable() <router_api-enable>` and
+    :ref:`vshard.router.disable() <router_api-disable>`.
+    The error object's name attribute is ``ROUTER_IS_DISABLED``.
+
+    The router is enabled by default. However, it is automatically and
+    forcefully disabled until the configuration is finished, as accessing the
+    router's methods at that time is not safe.
+
+    Manual disabling can be used, for example, if some preparatory work needs
+    to be done after calling :ref:`vshard.router.cfg() <router_api-cfg>` but
+    before the router's methods are available. It will look like this:
+
+    ..  code-block:: lua
+
+        vshard.router.disable()
+        vshard.router.cfg(...)
+        -- Some preparatory work here ...
+        vshard.router.enable()
+        -- vshard.router's methods are available now
