1. Remove br-int bridge on the Contorl node

   Code Block
   language text
   $ sudo ovs-vsctl del-br br-int

   The process will be unnecessary very soon.

2. Configure OpenstackSwitching application: network-cfg.json

   Code Block
   language text title network-cfg.json collapse true
   { "apps" : { "org.onosproject.openstackswitching" : { "openstackswitching" : { "do_not_push_flows" : "false", "neutron_server" : "http://OPENSTACK_CONROL_NODE_IP:9696/v2.0/", "keystone_server" : "http://OPENSTACK_CONROL_NODE_IP:5000/v2.0/", "user_name" : "admin", "password" : "nova" } }, "org.onosproject.dhcp" : { "dhcp" : { "ip": "10.0.0.1", "mac": "1a:2b:3c:4e:5e:6f", "subnet": "255.0.0.0", "broadcast": "10.255.255.255", "router": "10.0.0.1", "domain": "10.0.0.1", "ttl": "63", "lease": "300", "renew": "150", "rebind": "200", "delay": "3", "timeout": "150", "startip": "10.0.0.110", "endip": "10.0.0.130" } }, "org.onosproject.cordvtn" : { "cordvtn" : { "nodes" : [ { "hostname" : "compute-01", "ovsdbIp" : "COMPUTE_NODE_IP", "ovsdbPort" : "6640", "bridgeId" : "of:0000000000000001" }, { "hostname" : "compute-02", "ovsdbIp" : "COMPUTE_NODE_IP", "ovsdbPort" : "6640", "bridgeId" : "of:0000000000000002" }, { "hostname" : "network", "ovsdbIp" : "OPENSTACK_CONTROL_NODE_IP", "ovsdbPort" : "6640", "bridgeId" : "of:0000000000000003" } ] } } } }

   We need to configure the OpenstackSwitching application using the standard ONOS Network Configuration framework, network-cfg.json file.

   App field	Field name	Description
   org.onosproject.openstackswitching	do_not_push_flows	"true": it does not push any flow rules to OVS and works as just the Openstack interface. "false": it pushes all flow rules to OVS
   	neutron_server	URL to the neutron server
   	keystone_server	URL to the keystone server for authentication
   org.onosproject.dhcp	<all>	Sample DHCP domain information. You do not touch it. They are just samples and not really used,  but we need at least one.
   org.onosproject.cordvtn:cordvtn:nodes	cordvtn:nodes	Descriptions of hosts. We need to setup information of all hosts we have setup, which are control node and two compute nodes.
   	hostname	description of the host
   	ovsdbIp	IP address of the host
   	ovsdbPort	OVSDB Port: 6640, which is set via "ovs-vsctl set-manager" command
   	bridgeId	Datapath ID of the OVS switch in the host

   Copy the network-cfg.json file to ~/onos/tools/package/config. If you updated or just copied the file, then you need to compile the onos again to distribute the network-json file.

3. Compile and install ONOS

   Code Block
   language bash
   ~/onos$ mcis ~/onos$ onos-package ~/onos$ onos-install -f $OC1

   You need to set up you own cell information before you install the ONOS.

4. Login to the ONOS CLI and activate OpenstackSwitching application

   Code Block
   language text
   onos> app activate org.onosproject.openstackswitching

5. You can see the three devices (control node and two compute nodes) from ONOS CLI, if everything has been configured successfully.

   Code Block
   language text
   onos> devices id=of:0000000000000001, available=true, role=MASTER, type=SWITCH, mfr=Nicira, Inc., hw=Open vSwitch, sw=2.3.2, serial=None, managementAddress=10.40.101.116, protocol=OF_13, channelId=10.40.101.116:60019 id=of:0000000000000002, available=true, role=MASTER, type=SWITCH, mfr=Nicira, Inc., hw=Open vSwitch, sw=2.3.2, serial=None, managementAddress=10.40.101.176, protocol=OF_13, channelId=10.40.101.176:38230 id=of:0000000000000003, available=true, role=MASTER, type=SWITCH, mfr=Nicira, Inc., hw=Open vSwitch, sw=2.0.2, serial=None, managementAddress=10.40.101.156, protocol=OF_13, channelId=10.40.101.156:59094

6. Now everything is done. Enjoy OpenstackSwitching!!
