I am sorry for getting to this bug so late. I'll need some clarifications / information before I can understand the issue. 1) the exact commands you use to create ports / networks in OSP for all three cases mentioned (switchdev + vlan, switchdev + geneve, virtio + vlan). 2) how you assign FIPs to ports. 3) openstack port show / openstack network show for each. 4) ovn-nbctl show + ovn-sbctl show + ovs-ofctl dump-flows br-int for each scenario. I think this upstream bug may be relevant here: https://bugs.launchpad.net/neutron/+bug/1875852 Could you please check if the scenario described at the link is the same you are trying to achieve? Thanks. Hi Ihar, (In reply to Ihar Hrachyshka from comment #1) > I am sorry for getting to this bug so late.

Yes, the 4th scenario "4) SRIOV ports on VLAN tenant networks and N/S Neutron routing with and without FIPs" is what i was trying here. > Thanks.

Description of problem: Ping to floating ip associated with switchdev port from provider vlan network doesnt work. Same works well if switchdev port from geneve tenant network. Same works well if VirtIO port from provider vlan network. Version-Release number of selected component (if applicable): RHEL: rhel 8.4 Kernel: 4.18.0-305.12.1.el8_4.x86_64 Ovs: openvswitch2.15-2.15.0-26.el8fdp.x86_64 Ovn: ovn-2021-21.03.0-40.el8fdp.x86_64 rhosp-ovn-2021-4.el8ost.1.noarch How reproducible: Always Steps to Reproduce: 1. Attach floating ip to switchdev port of provider vlan network 2. Ping floating ip Actual results: Ping fails Expected results: Ping should works Additional info: This is DVR disabled environment. This may evenutally fall to core-ovn.
