Let us manually spawn a ``radvd`` daemon inside ``ipv6-router`` namespace to simulate an external router.
First of all, we will have to identify the ``ipv6-router`` namespace and move to the namespace.
+Please **NOTE** that in case of HA (High Availability) deployment model where multiple controller
+nodes are used, ``ipv6-router`` created in step **SETUP-SVM-11** could be in any of the controller
+node. Thus you need to identify in which controller node ``ipv6-router`` is created in order to manually
+spawn ``radvd`` daemon inside the ``ipv6-router`` namespace in steps **SETUP-SVM-24** through
+**SETUP-SVM-30**. The following command in Neutron will display the controller on which the
+``ipv6-router`` is spawned.
+
+.. code-block:: bash
+
+ neutron l3-agent-list-hosting-router ipv6-router
+
+Then you login to that controller and execute steps **SETUP-SVM-24**
+through **SETUP-SVM-30**
+
**SETUP-SVM-24**: identify the ``ipv6-router`` namespace and move to the namespace
.. code-block:: bash
