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.

$ sudo ovs-vsctl set-manager ptcp:6640

Confgiure br-int bridge using openstack-node-init command.

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.

$ 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}
        Port router
            Interface router
    ovs_version: "2.5.2"

3. Download sona-setup scripts as well.

$ git clone -b 1.13 https://github.com/sonaproject/sona-setup.git
$ cd sona-setup

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

...

• line 1, floatingCidr: Floating IP address ranges. It can be comma separated list.
• line 2, externalPeerMac: Remote peer router's MAC address.

45. Run createExternalRouter.sh. It will create emulated external peer router.

...

*Note that we don't use quagga app. We just use quagga container for convenience.

56. 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,
