    These local VLAN IDs on br-int are assigned separately on each
    compute or network node by neutron's openvswitch-agent, so you
    should be able to use any number of networks simultaneously in your
    deployment as long as no more than 4094 networks are active at once
    on any one node.<br>

                          <div>Maybe this is a simple question: is there
                            any limit on "tunnel_id_ranges" in Neutron
                            configuration? Say, can I configured it to
                            e.g., "1:10000" if I have 10000 tenants in
                            the cloud. I know VLAN is limited to 4094
                            tags.</div>
                          <div><br>
                          </div>
                          <div>I googled around this issue but found
                            that most commonly it  is configured to
                            default "1:1000".</div>

                  <div>There should not be a limit here, although the
                    code will verify the tunnel ID falls within an
                    allowed range for your tunnel protocol (currently
                    GRE or VXLAN).</div>
