### OpenStack + OpenDaylight network bridges

Hi everyone,

I'm working on a project that uses OpenDaylight to manage an OpenStack network. I've been following these instructions to set it up:

https://wiki.opendaylight.org/view/OpenStackandOpenDaylight

The setup seems to go smoothly. But once it's all done, there's a big problem: ODL doesn't create any sort of connection between the br-int bridges on the various nodes. For example, here's what OVS looks like on my compute node:

root@cp-1:~# ovs-vsctl show
Manager "tcp:192.168.0.1:6640"
is_connected: true
Bridge br-int
Controller "tcp:192.168.0.1:6633"
is_connected: true
fail_mode: secure
Port br-int
Interface br-int
Port "tap51c81deb-ae"
Interface "tap51c81deb-ae"
ovs_version: "2.3.2"


As you can see above (and also in the setup instructions) br-int is isolated. It has no physical or virtual interface. So when I launch an OpenStack instance on this compute node, it has no way of talking to the rest of the network.

It seems to me like ODL should be setting up some manner of connection between br-int and the rest of the network? Or is this something I have to set up manually? Or am I missing something totally different?

Would appreciate any ideas or suggestions!
