Hi, I'm trying to connect Openstack and Opendaylight.

Configurations:

Opendaylight (192.168.2.15) 0.4.4-Beryllium

In the distribution-karaf-0.4.4-Breryllium-SR4/etc/opendaylight/karaf directory, I have the file called 90-vtn-neutron.xml, which contains the following:

 bridgename=br-int
 portname=enp0s9
 protocols=OpenFlow13
 failmode=secure

I install the following features:

• odl-openflowplugin-all-li
• odl-vtn-manager
• odl-vtn-manager-neutron
• odl-vtn-manager-rest
• odl-dlux-all

Openstack: Version ROCKY I have 2 nodes: controller and compute (Each has 2 interafaces: enp0s8 and enp0s9)

Controller (enp0s8: 192.168.2.12 , enp0s9 10.0.0.4)

Now, the connection is working and if sudo ovs-vsctl show in compute and controller nodes, I can see the following:

Manager "tcp:192.168.2.15:6640"
   is_connected: true
Bridge br-ex
   Controller "tcp:192.168.2.15:6633"
      is_connected: true
   Port br-ex
      Interface br-ex
         type: internal
Bridge br-int
   Controller "tcp:192.168.2.15:6633"
      is_connected: true
   fail_mode: secure
   Port "enp0s9"
      Interface "enp0s9"
ovs_version: "2.9.2"

Actually, I don't know why the bridge br-ex appears (i just configured br-int in 90-vtn-neutron.xml.., but ok)

I can see the 4 OVSwitches in OpenDaylight dlux (br-int and br-ex of computer node and br-int and br-ex of controller node).

When I try to create a network in Openstack, it's fine. (Type: local ... (more)
