I notice that there are flow_mod flows on OVS which handle 1-to-1
translations between VLAN IDs and GRE/VXLAN tunnel IDs. Does it mean
the range of tunnel_ids is limited by VLAN tags?
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.

Hi All,
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.
I googled around this issue but found that most commonly it
is configured to default "1:1000".
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).
Thanks,
Kyle
