You've mentioned "OVS 1.04" before. There is no such version. I guess you mean 1.4.0. > and I have to say that after 780 GRE port additions OVS shows no > signs of slow down.

The "monitor" feature offers incremental updates, so that adding or removing ports should not be expensive. > Not an OVS issue but interesting to me none the > less.

Another option with sufficiently new OVS is creating only one tunnel with key=flow and then distinguishing between tunnels only in the flow table. _______________________________________________ discuss mailing list [email protected] http://openvswitch.org/mailman/listinfo/discuss
