Introduction
You will need:
- ONOS clusters installed and running, one for SONA and the others for vRouter. ONOS for vRouter runs on every gateway node.
- An OpenStack service installed and running ("stable/mitaka" version is used here)
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.
- 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 tunnel
- External network: used for North-South traffic, normally only the gateway node has a connectivity to this network
If you don't have enough network interfaces in your test environment, you can share the networks. You can also emulate the external router. The figure below shows one possible test environment used in the rest of this guide, where no actual external router exists but emulated one with Docker container.
Prerequisite
1. Install OVS to all nodes including compute and gateway. Make sure your OVS version is 2.3.0 or later. This guide works very well for me (don't forget to change the version in the guide to 2.3.0 or later).
2. Set OVSDB listening mode in your compute nodes. There are two ways. "compute_node_ip" below should be accessible address from the ONOS instance.
$ ovs-appctl -t ovsdb-server ovsdb-server/add-remote ptcp:6640:compute_node_ip
Or you can make the setting permanent by adding the following line to /usr/share/openvswitch/scripts/ovs-ctl, right after "set ovsdb-server "$DB_FILE" line. You need to restart the openvswitch-switch service.
set "$@" --remote=ptcp:6640
Either way, you should be able to see port "6640" is in listening state.
$ netstat -ntl Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN tcp 0 0 0.0.0.0:6640 0.0.0.0:* LISTEN tcp6 0 0 :::22
3. Check your OVSDB. It is okay If there's a bridge with name br-int, but note that SONA will add or update its controller, DPID, and fail mode.
$ sudo ovs-vsctl show cedbbc0a-f9a4-4d30-a3ff-ef9afa813efb ovs_version: "2.5.0"
ONOS-SONA Setup
1. Refer to the guide(SONA Network Configuration Guide) and write a network configuration for SONA. Place the network-cfg.json under tools/package/config/, build package, and then install ONOS. Here's an example cell configuration and commands.
onos$ cell ONOS_CELL=sona OCI=10.134.231.29 OC1=10.134.231.29 ONOS_APPS=drivers,openflow-base,openstackswitching,openstackrouting ONOS_GROUP=sdn ONOS_TOPO=default ONOS_USER=sdn ONOS_WEB_PASS=rocks ONOS_WEB_USER=onos onos$ buck build onos onos$ cp ~/network-cfg.json ~/onos/tools/package/config/ onos$ onos-package onos$ stc setup
Make sure to activate "only" the following ONOS applications.
ONOS_APPS=drivers,openflow-base,openstackswitching
If you want Neutron L3 service, enable openstackrouting, too.
ONOS_APPS=drivers,openflow-base,openstackswitching,openstackrouting
2. Check all the applications are activated successfully.
onos> apps -s -a * 4 org.onosproject.dhcp 1.7.0.SNAPSHOT DHCP Server App * 6 org.onosproject.optical-model 1.7.0.SNAPSHOT Optical information model * 12 org.onosproject.openflow-base 1.7.0.SNAPSHOT OpenFlow Provider * 19 org.onosproject.ovsdb-base 1.7.0.SNAPSHOT OVSDB Provider * 22 org.onosproject.drivers.ovsdb 1.7.0.SNAPSHOT OVSDB Device Drivers * 27 org.onosproject.openstackinterface 1.7.0.SNAPSHOT OpenStack Interface App * 28 org.onosproject.openstacknode 1.7.0.SNAPSHOT OpenStack Node Bootstrap App * 29 org.onosproject.scalablegateway 1.7.0.SNAPSHOT Scalable GW App * 30 org.onosproject.openstackrouting 1.7.0.SNAPSHOT OpenStack Routing App * 44 org.onosproject.openstackswitching 1.7.0.SNAPSHOT OpenStack Switching App * 50 org.onosproject.drivers 1.7.0.SNAPSHOT Default device drivers
OpenStack Setup
How to deploy OpenStack is out of scope of this documentation. Here, it only describes some configurations related to use SONA. All other settings are completely up to your environment.
Controller Node
1. Install networking-onos (Neutron ML2 plugin for ONOS) first.
$ git clone https://github.com/openstack/networking-onos.git $ cd networking-onos $ sudo python setup.py install
2. Specify ONOS access information. You may want to copy the config file to /etc/neutron/plugins/ml2/ where the other Neutron configuration files are.
# Configuration options for ONOS ML2 Mechanism driver [onos] # (StrOpt) ONOS ReST interface URL. This is a mandatory field. url_path = http://10.134.231.29:8181/onos/openstacknetworking # (StrOpt) Username for authentication. This is a mandatory field. username = onos # (StrOpt) Password for authentication. This is a mandatory field. password = rocks
URL path is changed from "onos/openstackswitching" to "onos/openstacknetworking" since 1.8.0.
3. Next step is to install and run OpenStack services. For DevStack users, use this sample DevStack local.conf to build OpenStack controller node. Make sure your DevStack branch is consistent with the OpenStack branches, "stable/mitaka" in this example.
[[local|localrc]] HOST_IP=10.134.231.28 SERVICE_HOST=10.134.231.28 RABBIT_HOST=10.134.231.28 DATABASE_HOST=10.134.231.28 Q_HOST=10.134.231.28 ADMIN_PASSWORD=nova DATABASE_PASSWORD=$ADMIN_PASSWORD RABBIT_PASSWORD=$ADMIN_PASSWORD SERVICE_PASSWORD=$ADMIN_PASSWORD SERVICE_TOKEN=$ADMIN_PASSWORD DATABASE_TYPE=mysql # Log SCREEN_LOGDIR=/opt/stack/logs/screen # Images IMAGE_URLS="http://cloud-images.ubuntu.com/releases/14.04/release/ubuntu-14.04-server-cloudimg-amd64.tar.gz,http://www.planet-lab.org/cord/trusty-server-multi-nic.img" FORCE_CONFIG_DRIVE=True # Networks Q_ML2_TENANT_NETWORK_TYPE=vxlan Q_ML2_PLUGIN_MECHANISM_DRIVERS=onos_ml2 Q_PLUGIN_EXTRA_CONF_PATH=/opt/stack/networking-onos/etc Q_PLUGIN_EXTRA_CONF_FILES=(conf_onos.ini) ML2_L3_PLUGIN=networking_onos.plugins.l3.driver.ONOSL3Plugin NEUTRON_CREATE_INITIAL_NETWORKS=False # Services enable_service q-svc disable_service n-net disable_service n-cpu disable_service tempest disable_service c-sch disable_service c-api disable_service c-vol # Branches GLANCE_BRANCH=stable/mitaka HORIZON_BRANCH=stable/mitaka KEYSTONE_BRANCH=stable/mitaka NEUTRON_BRANCH=stable/mitaka NOVA_BRANCH=stable/mitaka
If you use other deploy tools or build the controller node manually, please set the following configurations to Nova and Neutron configuration files. Set Neutron to use ONOS ML2 plugin and ONOS L3 service plugin.
core_plugin = neutron.plugins.ml2.plugin.Ml2Plugin service_plugins = networking_onos.plugins.l3.driver.ONOSL3Plugin dhcp_agent_notification = False
[ml2] tenant_network_types = vxlan type_drivers = vxlan mechanism_drivers = onos_ml2 [securitygroup] enable_security_group = True
Set Nova to use config drive for metadata service, so that we don't need to launch Neutron metadata-agent. And of course, set to use Neutron for network service.
[DEFAULT] force_config_drive = True network_api_class = nova.network.neutronv2.api.API security_group_api = neutron [neutron] url = http://10.134.231.28:9696 auth_strategy = keystone admin_auth_url = http://10.134.231.28:35357/v2.0 admin_tenant_name = service admin_username = neutron admin_password = [admin passwd]
Don't forget to specify conf_onos.ini when you start Neutron service.
/usr/bin/python /usr/local/bin/neutron-server --config-file /etc/neutron/neutron.conf --config-file /etc/neutron/plugins/ml2/ml2_conf.ini --config-file /opt/stack/networking-onos/etc/conf_onos.ini
Compute node
No special configurations are required for compute node other than setting network api to Neutron. For DevStack users, here's sample DevStack local.conf.
[[local|localrc]] HOST_IP=10.134.231.30 SERVICE_HOST=10.134.231.28 RABBIT_HOST=10.134.231.28 DATABASE_HOST=10.134.231.28 ADMIN_PASSWORD=nova DATABASE_PASSWORD=$ADMIN_PASSWORD RABBIT_PASSWORD=$ADMIN_PASSWORD SERVICE_PASSWORD=$ADMIN_PASSWORD SERVICE_TOKEN=$ADMIN_PASSWORD DATABASE_TYPE=mysql NOVA_VNC_ENABLED=True VNCSERVER_PROXYCLIENT_ADDRESS=$HOST_IP VNCSERVER_LISTEN=$HOST_IP LIBVIRT_TYPE=kvm # Log SCREEN_LOGDIR=/opt/stack/logs/screen # Services ENABLED_SERVICES=n-cpu,neutron # Branches NOVA_BRANCH=stable/mitaka KEYSTONE_BRANCH=stable/mitaka NEUTRON_BRANCH=stable/mitaka
If your compute node is a VM, try http://docs.openstack.org/developer/devstack/guides/devstack-with-nested-kvm.html this first or set LIBVIRT_TYPE=qemu
. Nested KVM is much faster than qemu
, if possible.
For manual set ups, set Nova to use Neutron as a network API.
[DEFAULT] force_config_drive = True network_api_class = nova.network.neutronv2.api.API security_group_api = neutron [neutron] url = http://10.134.231.28:9696 auth_strategy = keystone admin_auth_url = http://10.134.231.28:35357/v2.0 admin_tenant_name = service admin_username = neutron admin_password = [admin passwd]
Gateway node
No OpenStack service needs to be running on gateway nodes.
Node and ONOS-vRouter Setup
Single Gateway Node Setup
1. Push network-cfg.json after ONOS-SONA and OpenStack are ready, and check all COMPUTE type node state is COMPLETE with openstack-nodes command. Use openstack-node-check command for more detailed states of the node if it's INCOMPLETE. For GATEWAY type node, leave it in DEVICE_CREATED state. You'll need additional configurations explained later.
$ curl --user onos:rocks -X POST -H "Content-Type: application/json" http://10.134.231.29:8181/onos/v1/network/configuration/ -d @network-cfg.json
onos> openstack-nodes hostname=compute-01, type=COMPUTE, managementIp=10.134.231.30, dataIp=10.134.34.222, intBridge=of:00000000000000a1, routerBridge=Optional.empty init=COMPLETE hostname=compute-02, type=COMPUTE, managementIp=10.134.231.31, dataIp=10.134.34.223, intBridge=of:00000000000000a2, routerBridge=Optional.empty init=COMPLETE hostname=gateway-01, type=GATEWAY, managementIp=10.134.231.32, dataIp=10.134.33.224, intBridge=of:00000000000000a3, routerBridge=Optional[of:00000000000000b1] init=DEVICE_CREATED Total 3 nodes
For your information, pushing network config file triggers reinitialization of all nodes at once. It's no harm to reinitialize COMPLETE state node. If you want to reinitialize only a particular compute node, use openstack-node-init command with hostname.
2. In GATEWAY type nodes, Quagga and additional ONOS instance for vRouter is required. Download and install Docker first.
$ wget -qO- https://get.docker.com/ | sudo sh
3. Download script to help setup gateway node.
$ git clone https://github.com/hyunsun/sona-setup.git $ cd sona-setup
4. At first, write config file for setting up gateway node. Name it vRouterConfig.ini, place under sona-setup.
[DEFAULT] routerBridge = "of:00000000000000b1" #Unique device ID of the router bridge floatingCidr = "172.27.0.0/24" #Floating IP ranges dummyHostIp = "172.27.0.1" #Gateway IP address of the floating IP subnet quaggaMac = "fe:00:00:00:00:01" #Quagga MAC address quaggaIp = "172.18.0.254/30" #Quagga instance IP address gatewayName = "gateway-01" #Quagga instance name bgpNeighborIp = "172.18.0.253/30" #IP address of the external BGP router that quagga instance peered to asNum = 65101 #AS number of Quagga instance peerAsNum = 65100 #AS number of external BGP router uplinkPortNum = "26" #Port number of uplink interface
5. Next, run createJsonAndvRouter.sh which automatically create vrouter.json and runs ONOS container with vRouter application activated.
sona-setup$ ./createJsonAndvRouter.sh sona-setup$ sudo docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES e5ac67e62bbb onosproject/onos:1.6 "./bin/onos-service" 9 days ago Up 9 days 6653/tcp, 8101/tcp, 8181/tcp, 9876/tcp onos-vrouter
6. Next, run createQuagga.sh which automatically create volumes/gateway/zebra.conf
and volumes/gateway/bgpd.conf, update vrouter.json and run Quagga container based on those config files.
sona-setup$ ./createQuagga.sh sona-setup$ sudo docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 978dadf41240 onosproject/onos:1.6 "./bin/onos-service" 11 hours ago Up 11 hours 6653/tcp, 8101/tcp, 8181/tcp, 9876/tcp onos-vrouter 5bf4f2d59919 hyunsun/quagga-fpm "/usr/bin/supervisord" 11 hours ago Up 11 hours 179/tcp, 2601/tcp, 2605/tcp gateway-01

Note that the FPM connection IP should be the ONOS-vRouter container's eth0 IP address. Docker increments the IP address whenever a new container created, so normally it would be 172.17.0.2 but if you have problem with FPM connection later, please check this IP is correct.
If you check the result of ovs-ofctl show
, there should be a new port named quagga
on br-router
bridge.

7. If there's no external router or emulation of it in your setup, add another Quagga container which acts as an external router. You can just run createQuaggaRouter.sh which automatically volumes/gateway/zebra.conf
and volumes/gateway/bgpd.conf, modify vrouter.json and vRouterConfig.ini, and run Quagga router instance.

on br-router
bridge.

8. If everything's right, check fpm-connections
, hosts
and routes
. 172.18.0.253
is the external default gateway in this example. If you added interface and host for floating IP range, you should be able to see the host in the list.
onos> hosts id=FA:00:00:00:00:01/None, mac=FA:00:00:00:00:01, location=of:00000000000000b1/25, vlan=None, ip(s)=[172.18.0.253] id=FE:00:00:00:00:02/None, mac=FE:00:00:00:00:02, location=of:00000000000000b1/1, vlan=None, ip(s)=[172.27.0.1], name=FE:00:00:00:00:02/None onos> fpm-connections 172.17.0.3:52332 connected since 6m ago onos> next-hops ip=172.18.0.253, mac=FA:00:00:00:00:01, numRoutes=1 onos> routes Table: ipv4 Network Next Hop 0.0.0.0/0 172.18.0.253 Total: 1 Table: ipv6 Network Next Hop Total: 0
9. Add route for floating IP range manually and check the route is added.
onos> route-add 172.27.0.0/24 172.27.0.1 onos> routes Table: ipv4 Network Next Hop 0.0.0.0/0 172.18.0.253 172.27.0.0/24 172.27.0.1 Total: 2 Table: ipv6 Network Next Hop Total: 0 onos> next-hops ip=172.18.0.253, mac=FA:00:00:00:00:01, numRoutes=1 ip=172.27.0.1, mac=FE:00:00:00:00:02, numRoutes=1
10. Now you should be able to see the gateway node is in COMPLETE state when you re-trigger node initialization. You can either run command openstack-node-init gateway-01 or push the network configuration file again.
onos> openstack-node-init gateway-01
Or
$ curl --user onos:rocks -X POST -H "Content-Type: application/json" http://10.134.231.29:8181/onos/v1/network/configuration/ -d @network-cfg.json
onos> openstack-nodes hostname=compute-01, type=COMPUTE, managementIp=10.134.231.30, dataIp=10.134.34.222, intBridge=of:00000000000000a1, routerBridge=Optional.empty init=COMPLETE hostname=compute-02, type=COMPUTE, managementIp=10.134.231.31, dataIp=10.134.34.223, intBridge=of:00000000000000a2, routerBridge=Optional.empty init=COMPLETE hostname=gateway-01, type=GATEWAY, managementIp=10.134.231.32, dataIp=10.134.33.224, intBridge=of:00000000000000a3, routerBridge=Optional[of:00000000000000b1] init=COMPLETE hostname=gateway-02, type=GATEWAY, managementIp=10.134.231.33, dataIp=10.134.33.225, intBridge=of:00000000000000a4, routerBridge=Optional[of:00000000000000b2] init=COMPLETE Total 4 nodes
Multiple Gateway Nodes Setup
SONA allows multiple gateway nodes for HA as well as scalability. By simply modifying routerBridge, quaggaMac, quaggaIp, gatewayName, and bgpNeighborIp in vRouterConfig.ini, you can easily set multiple gateway nodes up. In this scenario, each gateway node should have unique IP and MAC address for peering so that the upstream router can handle each of them as a different router. ONOS scalable gateway application is responsible for taking upstream packet through one of the gateway nodes, and the upstream router is responsible for taking downstream packet through one of the gateway nodes.
The following is an example configuration of the second gateway node.
[DEFAULT] routerBridge = "of:00000000000000b2" floatingCidr = "172.27.0.0/24" dummyHostIp = "172.27.0.1" quaggaMac = "fe:00:00:00:00:03" quaggaIp = "172.18.0.249/30" gatewayName = "gateway-02" bgpNeighborIp = "172.18.0.250/30" asNum = 65101 peerAsNum = 65100 uplinkPortNum = "26"
Now configure the upstream router as below.
router bgp 65100 timers bgp 3 9 distance bgp 20 200 200 maximum-paths 2 ecmp 2 neighbor 172.18.0.254 remote-as 65101 neighbor 172.18.0.254 maximum-routes 12000 neighbor 172.18.0.250 remote-as 65101 neighbor 172.18.0.250 maximum-routes 12000 redistribute connected

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.
$ 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.

3. Set url_path to point to the proxy server in Neutron ML2 ONOS mechanism driver configuration and restart Neutron.
# Configuration options for ONOS ML2 Mechanism driver [onos] # (StrOpt) ONOS ReST interface URL. This is a mandatory field. url_path = http://[proxy-server IP]:8181/onos/openstackswitching # (StrOpt) Username for authentication. This is a mandatory field. username = onos # (StrOpt) Password for authentication. This is a mandatory field. password = rocks
4. Stop one of the ONOS instance and check everything works fine.
$ onos-service $OC1 stop
Scale Out Nodes
Scale out compute or gateway node is easy. Just add the new node to the SONA network config and update the config to the ONOS-SONA.
