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 dir="ltr">Hi All,
<div><br>
</div>
<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>
