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.

Image Removed

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).

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.

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. 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. Please

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.

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. For If you have no physical peer switch, for GATEWAY type node, leave it in the state of the node would be DEVICE_CREATED state. You'll need additional configurations explained later for gateway nodes.

Switch Setup

Single Gateway Node Setup

1. For all GATEWAY type nodes, Quagga and additional ONOS instance is required. Let's download and install Docker and required python packages first.

Code Block

language	bash

$ wget -qO- https://get.docker.com/ | sudo sh
$ sudo apt-get install python-pip -y
$ sudo pip install oslo.config
$ sudo pip install ipaddress

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

language	bash

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)2. Download sona-setup scripts as well.

Code Block

language	bash

$ git clone https://github.com/sonaproject/sona-setup.git
$ cd sona-setup

3. Write vRouterConfig.ini and place it under sona-setup directory.

Code Block

title	vRouterConfig.ini
linenumbers	true

[DEFAULT]
routerBridge = "of:00000000000000b1"
floatingCidr = "172.27.0.0/24,172.28.0.0/24"
localPeerMac = "fe:00:00:00:00:01"
localPeerIp = "172.18.0.254/30"
vRouterName = "gateway-01"
bgpNeighborIp = "172.18.0.253/30"
localAsNum = 65101
remoteAsNum = 65100
uplinkPortNum = "3"

line 3, floatingCidr: Floating IP address ranges. It can be comma separated list.
line 4, localPeerMac: Local MAC address used for peering. It should be unique across the system.
line 5, localPeerIp: Local IP address used for peering. It should be unique across the system.

line 8, localAsNum: Local AS number.
line 9, remoteAsNum: Remote peer's AS number.
line 10, uplinkPortNum: Port number of uplink interface on br-router bridge.

4. Run createJsonAndvRouter.sh. It will create configurations for vRouter, vrouter.json, and then brings up ONOS container with vRouter application activated.

Swtich(config)#interface vlan 20
Swtich(config-vlan-20)ip address 172.27.0.1/24

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

language	bash

$ 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

3. Download sona-setup scripts as well.

Code Block

language	bash

$ git    Up 9 days           6653/tcp, 8101/tcp, 8181/tcp, 9876/tcp   onos-vrouter

5. Next, run createQuagga.sh. It will create Quagga configurations, zebra.conf and bgpd.conf with floating IP ranges, and then brings up Quagga container. It also re-generates vrouter.json with Quagga container's port number and restart ONOS container.

clone https://github.com/sonaproject/sona-setup.git
$ cd sona-setup

4. Write externalRouterConfig.ini and place it under sona-setup directory.

Code Block

title	externalRouterConfig.ini

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.

Next, set the controller of the br-router to the ONOS controller container executed by the script.

Code Block
$ sudo ovs-vsctl set-controller br-router tcp:172.17.0.2:6653

Pleaset note that each gateway has its own ONOS controller, which is different from the main ONOS controller. In most of the case, the ONOS container is executed with the IP address of 172.17.0.2. However, if the IP is taken for some reasons, then another IP address can be assigned. So, please check the IP address after running the vRouter script, as below.

8. Add additional route for the floating IP ranges manually and check routes again.

Code Block

onos> routes

9. Everything's ready! Try init the gateway node again by running openstack-node-init command from ONOS-SONA.

Code Block
onos> openstack-node-init gateway-01

Multiple Gateway Nodes Setup

SONA allows multiple gateway nodes for scalability as well as HA. Adding additional gatewy node is very easy. Just add the node configuration to ONOS-SONA network configuration and then try init to make the node state DEVICE_CREATED. And then do the same steps with the above single gateway node setup in the new gateway node. Don't forget to put unique value for quaggaMac and quaggaIp. Here is an example configuration of the second gateway node.

Code Block

title	vRouterConfig.ini

[DEFAULT]
routerBridge = "of:00000000000000b2"
floatingCidr = "172.27.0.0/24"
floatingGateway = "172.27.0.1"
localPeerMac = "fe:00:00:00:00:03"
localPeerIp = "172.18.0.250/30"
vRouterName = "gateway-02"
bgpNeighborIp = "172.18.0.249/30"
localAsNum = 65101
remoteAsNum = 65100
uplinkPortNum = "3"

You'll have to enable multipath in your external router as well.

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.
