The 1.1.x release series is no longer maintained. Please consider upgrading. > I have created dp0 and attached normal eth interfaces to it. Dp0 is > controlled by NOX. This far everything works fine.

As you have discovered, they do not work with newer versions. > All the examples I am able to find seems to succeed without any -id > option. What am I missing here? Do I need -id option?

If you want to use this approach (which is more difficult than the other approach described later), then --id is documented in ovs-vsctl(8). > Some examples use also ovs-vsctl -add-port br0 gre0 -set Interface gre0 > type=gre options:remote_ip=1.2.3.4.

I'm not sure it's worth describing the relationship in detail, because you can disregard the name dp0 entirely. Only the name br0 is important. Furthermore, newer versions of OVS don't use the dp0 naming at all. > Do you have any ideas what is wrong and what should I try next? "ovs-vsctl add-port br0 gre0 -- set Interface gre0 type=gre options:remote_ip=1.2.3.4" should work. _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss
