+Multus
+===========
+
+Multus is a meta CNI plugin that provides multiple network interface support to
+pods. For each interface, Multus delegates CNI calls to secondary CNI plugins
+such as Calico, macvlan, etc.
+
+See [multus documentation](https://github.com/intel/multus-cni).
+
+## Multus installation
+
+Since Multus itself does not implement networking, it requires a master plugin, which is specified through the variable `kube_network_plugin`. To enable Multus an additional variable `kube_network_plugin_multus` must be set to `true`. For example,
+```
+kube_network_plugin: calico
+kube_network_plugin_multus: true
+```
+will install Multus and Calico and configure Multus to use Calico as the primary network plugin.
+
+## Using Multus
+
+Once Multus is installed, you can create CNI configurations (as a CRD objects) for additional networks, in this case a macvlan CNI configuration is defined. You may replace the config field with any valid CNI configuration where the CNI binary is available on the nodes.
+
+```
+cat <<EOF | kubectl create -f -
+apiVersion: "k8s.cni.cncf.io/v1"
+kind: NetworkAttachmentDefinition
+metadata:
+  name: macvlan-conf
+spec:
+  config: '{
+      "cniVersion": "0.3.0",
+      "type": "macvlan",
+      "master": "eth0",
+      "mode": "bridge",
+      "ipam": {
+        "type": "host-local",
+        "subnet": "192.168.1.0/24",
+        "rangeStart": "192.168.1.200",
+        "rangeEnd": "192.168.1.216",
+        "routes": [
+          { "dst": "0.0.0.0/0" }
+        ],
+        "gateway": "192.168.1.1"
+      }
+    }'
+EOF
+```
+
+You may then create a pod with and additional interface that connects to this network using annotations. The annotation correlates to the name in the NetworkAttachmentDefinition above.
+
+```
+cat <<EOF | kubectl create -f -
+apiVersion: v1
+kind: Pod
+metadata:
+  name: samplepod
+  annotations:
+    k8s.v1.cni.cncf.io/networks: macvlan-conf
+spec:
+  containers:
+  - name: samplepod
+    command: ["/bin/bash", "-c", "sleep 2000000000000"]
+    image: dougbtv/centos-network
+EOF
+```
+
+You may now inspect the pod and see that there is an additional interface configured:
+
+```
+$ kubectl exec -it samplepod -- ip a
+```
