Hi All,

Context:
  openstack-ansible tag:   14.0.1
  ML2 plug-in:   OpenvSwitch
  Project / External networks:   VLAN
  OS:  Ubuntu 16.0.4

I would like to implement OVS with VLANs following these 2 docs [1][2] but
things didn't work for me. I cannot ping my provider network:

root at node01-utility-container-edc0f67a:~# *openstack server list*
WARNING: openstackclient.common.utils is deprecated and will be removed
after Jun 2017. Please use osc_lib.utils

root at node01-utility-container-edc0f67a:~# *ping 10.1.4.103*
PING 10.1.4.103 (10.1.4.103) 56(84) bytes of data.

>From 10.1.200.25 icmp_seq=2 Destination Host Unreachable
>From 10.1.200.25 icmp_seq=3 Destination Host Unreachable


This is how my OpenvSwitch configuration looks:
root at node01:~# *ovs-vsctl show*
29613dde-944b-4449-ab09-af906a6f74c6
    Manager "ptcp:6640:127.0.0.1"
        is_connected: true
    Bridge br-int
        Controller "tcp:127.0.0.1:6633"
            is_connected: true
        fail_mode: secure
        Port int-br-provider
            Interface int-br-provider
                type: patch
                options: {peer=phy-br-provider}
        Port br-int
            Interface br-int
                type: internal
        Port "qvobb7afbfb-18"
            tag: 1
            Interface "qvobb7afbfb-18"
    Bridge br-provider
        Controller "tcp:127.0.0.1:6633"
            is_connected: true
        fail_mode: secure
        Port phy-br-provider
            Interface phy-br-provider
                type: patch
                options: {peer=int-br-provider}
        Port br-provider
            Interface br-provider
                type: internal
    ovs_version: "2.6.0"


Please advice on what might be wrong on my setup.

Thank you,
Hamza
