Introduction
Note that this instructions assume you’re familiar with ONOS and OpenStack, and do not provide a guide to how to install or trouble shooting these services. However, If you aren’t, please find a guide from ONOS(http://wiki.onosproject.org) and OpenStack(http://docs.openstack.org), respectively.
The example deployment depicted in the above figure uses three networks with an external router.
- Management network: used for ONOS to control virtual switches, and OpenStack to communicate with nova-compute agent running on the compute node
- Data network: used for East-West traffic via VXLAN, GRE or GENEVE tunnel
- External network: used for North-South traffic, normally only gateway nodes have an access to this network
All networks can share a network interface in case your test machine does not have enough interfaces. You can also emulate external router. The figure below shows an example test environment used in the rest of this guide with emulated external router and two network interfaces, one for sharing management and external, and the other for data.
Prerequisite
1. Install OVS to all nodes including compute and gateway. Make sure your OVS version is 2.3.0 or later (later than 2.5.0 is recommended). Refer to this guide for updating OVS (don't forget to change the version in the guide).
Note |
---|
In ONOS version 1.11 (Loon) or later, stateful NAT feature is included, which is disabled by default. If you want to use the stateful NAT feature, you have to install OVS 2.6 or later. |
2. Set OVSDB listening mode. Note that "compute_node_ip" in the below command should be an address accessible from the ONOS instance.
Code Block | ||
---|---|---|
| ||
$ ovs-appctl -t ovsdb-server ovsdb-server/add-remote ptcp:6640:[compute_node_ip] |
If you want to make the setting permanent, add the following line to /usr/share/openvswitch/scripts/ovs-ctl, right after "set ovsdb-server "$DB_FILE" line. You'll need to restart the openvswitch-switch service after that.
Code Block |
---|
set "$@" --remote=ptcp:6640 |
Now you should be able to see port "6640" is in listening state.
Code Block | ||
---|---|---|
| ||
$ netstat -ntl
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State

tcp 0 0 0.0.0.0:6640 0.0.0.0:* LISTEN
tcp6 0 0 :::22 |
3. Check your OVS state. It is recommended to clean up all stale bridges used in OpenStack including br-int, br-tun, and br-ex if there is any. Note that SONA will add required bridges via OVSDB once it is up.
Code Block | ||
---|---|---|
| ||
$ sudo ovs-vsctl show
cedbbc0a-f9a4-4d30-a3ff-ef9afa813efb
ovs_version: "2.8.2" |
OpenStack Setup
How to deploy OpenStack is out of scope of this documentation. Here, it only describes configurations related to use SONA. All other settings are completely up to your environment.
Controller Node
Note |
---|
The guide is based on OpenStack Ocata/Pike version. If you want to install Newton version of OpenStack, please refer to here <TBA>. |
1. The first step is installing networking-onos. Please create '/opt/stack' folder and install networking-onos in /opt/stack as follows.
Code Block |
---|
/opt/stack$ git clone --branch [stable/ocata or stable/pike] https://github.com/openstack/networking-onos.git |
Next, please create a file /opt/stack/networking-onos/etc/conf_onos.ini using the following template. Please set the IP_ADDRESS_OF_ONOS to host IP address of ONOS controller.
Code Block | ||||
---|---|---|---|---|
| ||||
# Configuration options for ONOS ML2 Mechanism driver
[onos]
# (StrOpt) ONOS ReST interface URL. This is a mandatory field.
url_path = http://IP_ADDRESS_OF_ONOS:8181/onos/openstacknetworking
# (StrOpt) Username for authentication. This is a mandatory field.
username = onos
# (StrOpt) Password for authentication. This is a mandatory field.
password = rocks |
2. The next step is installing and running OpenStack services. For DevStack users, use the following sample DevStack local.conf to build OpenStack controller node. Make sure your DevStack branch is consistent with the OpenStack branch, "stable/ocata" for example.
Code Block | ||||
---|---|---|---|---|
| ||||
$ git clone -b [stable/ocata or stable/pike] https://git.openstack.org/openstack-dev/devstack |
The following is the example of local.conf. Please set the IP addresses correctly, and the network setting should be set properly as below.(Branches can be modified to stable/queens or stable/rocky for your wish)

Post Installation Setup
After installing OpenStack completely, please run the following configuration in the OpenStack controller node. It is required for OpenStack Ocata version, NOT because of SONA. Please replace OPENSTACK_CONTROLLER_HOST_IP to the correct IP address.
Code Block |
---|
$ nova-manage cell_v2 map_cell0 --database_connection 'mysql+pymysql://root:nova@OPENSTACK_CONTROLLER_HOST_IP/nova_cell0?charset=utf8'
$ nova-manage cell_v2 simple_cell_setup --transport-url rabbit://stackrabbit:nova@OPENSTACK_CONTROLLER_HOST_IP:5672/
$ nova-manage cell_v2 discover_hosts |
Gateway node
No OpenStack service is required for a gateway node.
ONOS-SONA Setup
1. Refer to SONA Network Configuration Guide and write a network configuration file, typically named network-cfg.json. Place the configuration file under tools/package/config/, build, create package, and then install ONOS.
Note |
---|
Note that following tutorial is relevant only for building SONA apps against BUCK tool, and this only works from ONOS 1.13.0. So we strongly recommend the user to use ONOS 1.13.0 or above, if you would like to use BUCK to build SONA apps. For some reasons, if you have to use ONOS below 1.12.0, please use MAVEN to build the ONOS. |
Code Block |
---|
# SONA cluster (1-node)
export OC1=onos-01
export ONOS_APPS="drivers,openflow-base,openstacknetworking" |
In case you are using cell, here's example cell file for 3-node cluster
Code Block |
---|
export OC1=172.27.0.7
export OC2=172.27.0.8
export OC3=172.27.0.10
export ONOS_APPS="drivers,openflow-base,openstacknetworking" |

3. Check all nodes are registered and all COMPUTE type node's states are COMPLETE with openstack-nodes command. Use openstack-node-check command for more detailed states if the state is INCOMPLETE. If you want to reinitialize only a particular compute node, use openstack-node-init command with hostname. If you have no physical peer switch, for GATEWAY type node, the state of the node would be DEVICE_CREATED state. You'll need additional configurations explained later for gateway nodes.
Code Block |

Total 3 nodes |
Switch Setup
For switch to which Gatewy Node is connected, vlan and trunk setup is required.
1. Suppose we chose '172.27.0.1/24' as floating IP range and Gateway Nodes are connected to switch via port 2,3. And you decided to assign vlan number 20 to floating IP range. In that case, switch setup should be like below(Arista syntax).
Code Block | ||
---|---|---|
| ||
Swtich(config)#interface vlan 20
Swtich(config-vlan-20)ip address 172.27.0.1/24
Swtich(config-vlan-20)no shutdown
Swtich(config)#interface ethernet 2-3
Swtich(config-if-Et1-2)#switchport mode trunk
Swtich(config-if-Et1-2)#switchport trunk allowed vlan 20
Swtich(config-if-Et1-2)#switchport trunk native vlan tag 20 |
2. If you need multiple floating IP ranges, for example 172.27.1.1/24 with vlan 200, additional setup is required(Arista syntax).
Code Block | ||
---|---|---|
| ||
Swtich(config)#interface vlan 20
Swtich(config-vlan-20)ip address 172.27.0.1/24
Swtich(config-vlan-20)no shutdown
Swtich(config)#interface vlan 200
Swtich(config-vlan-20)ip address 172.27.1.1/24
Swtich(config-vlan-20)no shutdown
Swtich(config)#interface ethernet 2-3
Swtich(config-if-Et1-2)#switchport mode trunk
Swtich(config-if-Et1-2)#switchport trunk allowed vlan 20-21
Swtich(config-if-Et1-2)#switchport trunk native vlan tag 20 |
Gateway Node Setup
Basically there's no additional setup is required on Gateway nodes. Those are for whom doen't have physical peer switch.
1. Let's download and install Docker first.
Code Block | ||
---|---|---|
| ||
$ wget -qO- https://get.docker.com/ | sudo sh |
2. Install and configure OVS
OVS version depends on the SONA features you want to enable. If you want staful NAT features, you have to install OVS 2.6 or higher. Otherwise, you can install OVS 2.5.
Then, set the OVSDB listener port as 6640 so that ONOS can intiated OVSDB connection.
Code Block |
---|
$ sudo ovs-vsctl set-manager ptcp:6640 |
Confgiure br-int bridge using openstack-node-init command.
Code Block |
---|
onos> openstack-node-init gateway-01
Initializing gateway-01
Done. |
You can check if br-int bridge is configured correctly using ovs-vsctl command, as follows.
Code Block |
---|
$ sudo ovs-vsctl show
427d7ee0-218f-4d68-b503-a5639a367357
Manager "ptcp:6640"
Bridge br-int
Controller "tcp:10.1.1.30:6653"
is_connected: true
fail_mode: secure
Port br-int
Interface br-int
Port vxlan
Interface vxlan
type: vxlan
options: {key=flow, remote_ip=flow}
ovs_version: "2.5.2" |
3. Download sona-setup scripts as well.
Code Block | ||
---|---|---|
| ||
$ git clone https://github.com/sonaproject/sona-setup.git
$ cd sona-setup |
4. Write externalRouterConfig.ini and place it under sona-setup directory.
Code Block | ||||
---|---|---|---|---|
| ||||
floatingCidr = "172.27.0.1/24"
externalPeerMac = "fa:00:00:00:00:01" |
- line 1, floatingCidr: Floating IP address ranges. It can be comma separated list.
- line 2, externalPeerMac: Remote peer router's MAC address.
5. Run createExternalRouter.sh. It will create emulated external peer router.
Code Block |
---|
sona-setup$ ./createExternalRouter.sh
sona-setup$ sudo docker ps

*Note that we don't use quagga app. We just use quagga container for convenience.
6. When every work is done, you create router with appropriate extenal network that floating IP range is assigned. Then you execute below CLI to check MAC learning for external peer rotuer is working well,
Code Block |
---|
onos> openstack-peer-routers
Router IP Mac Address VLAN ID
172.27.0.1 FA:00:00:00:00:01 None |
HA Setup
Basically, ONOS itself provides HA by default when there are multiple instances in the cluster. This section describes how to add a proxy server beyond the ONOS cluster, and make use of it in Neutron as a single access point of the cluster. For the proxy server, we used the HA proxy server (http://www.haproxy.org) here.
1. Install HA proxy.
Code Block | ||
---|---|---|
| ||
$ sudo add-apt-repository -y ppa:vbernat/haproxy-1.5
$ sudo add-apt-repository -y ppa:vbernat/haproxy-1.5
$ sudo apt-get update
$ sudo apt-get install -y haproxy |
2. Configure HA proxy.
