Yeah, what I mean is tunnel network between instance when instance
communicate using selfservice network, can I specify from which host
interface/NIC that traffic goes through? I found this: `ovs-vsctl set open
. external-ids:ovn-encap-ip=IP_ADDRESS` is it righ?

And btw, what is the best practise when using OVN? Did I need setup bridge
for overlay interface and provider interface on my controller too? Since,
as my understanding, inbound/outbound will have direct access from compute
node by default on OVN. And in this guide [1] bridge only configured on
compute nodes.
