You can have multiple tunnels between the same endpoints if they are distinguished by key.

It's not as straightforward as it might seem while maintaining good abstraction. ovs-vsctl writes into the database, which only enforces some basic constraints. ovs-vswitchd then picks up the config, does the actual port creation, and generates those log messages. Patches are, of course, welcome. _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss_openvswitch.org
