Hey, Not sure what specifically is wrong at this point (as not really great expert about ovn at the moment), but would like to ask some more questions which might be relevant. 1. In openstack_user_config how have you defined network-northd_hosts / network-gateway_hosts ? 2. I do see couple of plugins that are not compatible with ovn at least not on existing stable releases, including vpnaas, fwaas, and not sure about neutron_dynamic_routing.services.bgp.bgp_plugin.BgpPlugin since another project intends to provide same functionality: https://opendev.org/openstack/ovn-bgp-agent And that one does not work out of the box right now - I was about to check on what's needed to get it working and land support for the upcoming release. 3. I'm also not sure about provided mappings, since it seems you wanna have both flat and vlan network, while providing only 1 mapping. In ovs at least (I think ovn is same here) if you have only 1 interface for both cases (flat and vlan) - the only way to have both is map "flat" network as tagged vlan. As interface is added to the bridge and then can't be re-used as other "provider" type. On Tue, Jan 23, 2024, 20:17 jjjamesg <jjjamesg@proton.me> wrote:
I can't for the life of me get external connectivity working, openstack itself works i just cant get external connectivity working,
I can see ovs has created br-ex with bond1 attached. ovs-vsctl get open . external_ids:ovn-bridge-mapping shows: "physnst1:br-ex"
I have tried creating the network with both:
openstack network create --share --external --provider-physical-network physnet1 --provider-network-type vlan --provider-segment 233 public openstack network create --share --external --provider-physical-network physnet1 --provider-network-type flat publicnet-flat
Only errors i can see is in the neutron container when i try and either create an instance on said network or attach a fip is is: (similar errors from a vlan type network this is just the error i pulled at the time)

I just cant figure out WHY this isn't working..
Below is my config:
############# ### /etc/network/interfaces: #############
auto bond1 iface bond1 inet manual bond-slaves eno2 eno4 bond-mode 802.3ad bond-miimon 100 bond-downdelay 200 bond-updelay 200 bond-lacp-rate 1 mtu 9000
auto bond1.30 iface bond1.30 inet manual vlan-raw-device bond1

Bond1 is a trunk port (no native vlan), that has access to both overlay vlan and the 232:332 vlan range which both work when setting either network as a bridge on bond1 so connectivity is there.
I have network-northd/gateway_hosts defined as well as:
neutron_neutron_conf_overrides: ovn: enable_distributed_floating_ip: True
openstack_host_specific_kernel_modules: - name: "openvswitch" pattern: "CONFIG_OPENVSWITCH"
This should by all accounts just work, but for some reason for me it's not, what steps have i missed?
