[ovs-discuss] Dynamic GRE? Tunnel per VM

[Holger Winkelmann [TP]]

Hi,

We are just working with openvswitch for an ISP like Access Network Scenario.
We plan to define flows per connected Client (per MAC or IP). Further we want
to establish multiple Tunnel, conceptionally one tunnel per Flow (Client) and
send the traffic over a WAN.

Is there a way to dynamical create Tunnels per Flow via OPenFlow Extensions or
configuration Protocol?

We read about having "thousands of GRE tunnels" in the OVS specs but have not seen
how to dynamical set up them.

Thanks for any advise,

Holger
