[neutron] How to specify overlay network interface when using OVN and Geneve?
Hi, I have used my google fu but I cant find any reference. Just want to know how to specify overlay network when Im using geneve as my overlay protocol?
Hi, You can do that by configuring bridge_mappings on compute node(s). It is described in the doc [1]. On Fri, Aug 14, 2020 at 09:13:23PM +0700, Popoi Zen wrote:

Hi,
You can do that by configuring bridge_mappings on compute node(s). It is described in the doc [1]. when they said overlay network i think they meant the geneve tunnels in which casue you contole the interface that is used by adjusting your routing table to use the interface you desire.

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.

I am using Kolla Ansible that deploys OVN well for me. You can set tunnel_interface to specify the tunnel interface. Tony
