+Address Assignment
+==================
+
+.. tip::
+    We strongly recommend you to setup DHCP relay and configure the hosts to **obtain address via DHCP**.
+
+DHCP Relay
+----------
+
+
+Static IP
+---------
+Although we strongly recommend to use `DHCP Relay`_ for IP assignment,
+it is also possible to statically configure the IP address and route on the host.
+
+1. **Configure the IP address and subnet mask**
+
+   Make sure the IP address and the subnet mask on the fabric network interface of the host is consistent with
+   the information in the Network Configuration section. For example, you can run
+
+   .. code-block:: console
+
+       # ip addr add 10.0.0.1/24 dev mlx0
+
+2. **Configure the default route**
+
+   Make sure you change the default route of the host to the interface IP of the leaf switch it connects to.
+   For example, you can run
+
+   .. code-block:: console
+
+       # ip route add default via 10.0.0.254
+
+   .. note::
+       In the case that you want to keep default route through the management network,
+       you need to add routes to all other subnets in the  network one by one.
+
+3. **Trigger host learning**
+
+   We need to let ONOS learn the host in order to program corresponding flows and groups.
+   This is automatically done as part of the DHCP process.
+   However, we need to manually triggers it by sending an ARP or ND packet if the host is configured to use static IP.
+
+   .. code-block:: console
+
+       # arping -c 1 ${GATEWAY_IP}
+
+   .. code-block:: console
+
+       # ndsend ${HOST_IP} ${INTF}
