[kolla-ansible] OVS br-ex configuration for OVN SNAT gateway along with HAProxy
Hi, My goal is to have OVN SNAT gateway (with OVS bridge) and HAProxy co-exist. Here is the networking configuration (partial) before deployment. eth1, no address, neutron_external_interface eth1.40, external address, kolla_external_vip_interface After deployment, I'd like to see this. br-ex eth1 eth1.40 tag 40 eth1.40 with external address But actually, only eth1 is put on br-ex by Kolla Ansible. Need eth1.40 on br-ex, because the external network is also one of the provider networks. Need eth1 on br-ex, to support other provider networks (different VLANs). It works fine when deploy with TripleO with os-net-config. Is it supported by Kolla Ansible? It seems Kolla Ansible only puts one interface (neutron_external_interface) on br-ex? I know a few workarounds in case that's not supported, just want to confirm. Thanks! Tony

Thank you Danny for pointing it out! I somehow missed it when going through doc. Read it again, test and looked into playbook. It seems that's not what I need. [1] doesn't add multiple interfaces onto one bridge. It actually adds one interface onto one bridge, but there could be multiple pairs. This is also confirmed by playbook [2]. Also, the limitation of [3] is an issue for me. Hopefully this can be supported in the future. Thanks! Tony [1] https://docs.openstack.org/kolla-ansible/latest/reference/networking/neutron...
