In OVS 1.10 and later, a tunnel port has pretty minimal requirements. At a guess, a few thousand should not be a problem. Tunnel monitoring (CFM or BFD) is more expensive than tunnels themselves. If you think there's a bug causing ports not to be created, please report it. But ovs-vsctl just reports what's in the OVSDB database, and OVSDB is pretty well tested, so we would need some real details. _______________________________________________ discuss mailing list [email protected] http://openvswitch.org/mailman/listinfo/discuss
