Engineering Team, which is subscribed to neutron. https://bugs.launchpad.net/bugs/1995078 Title: OVN: HA chassis group priority is different than gateway chassis priority Status in kolla-ansible: New Status in kolla-ansible wallaby series: New Status in kolla-ansible xena series: New Status in kolla-ansible yoga series: New Status in kolla-ansible zed series: New Status in neutron: Confirmed Bug description: OpenStack release affected - Wallaby, Xena and Yoga for sure OVN version: 21.12 (from CentOS NFV SIG repos) Host OS: CentOS Stream 8 Neutron creates External ports for bare metal instances and uses ha_chassis_group. Neutron normally defines a different priority for Routers LRP gateway chassis and ha_chassis_group. I have a router with two VLANs attached - external (used for internet connectivity - SNAT or DNAT/Floating IP) and internal VLAN network hosting bare metal servers (and some Geneve networks for VMs). If an External port’s HA chassis group active chassis is different than gateway chassis (external vlan network) active chassis - those bare metal servers have intermittent network connectivity for any traffic going through that router. In a thread on ovs-discuss ML - Numan Siddique wrote that "it is recommended that the same controller which is actively handling the gateway traffic also handles the external ports" More information in this thread - https://mail.openvswitch.org/pipermail/ovs- discuss/2022-October/052067.html To manage notifications about this bug go to: https://bugs.launchpad.net/kolla-ansible/+bug/1995078/+subscriptions -- Mailing list: https://launchpad.net/~yahoo-eng-team Post to : yahoo-eng-team@lists.launchpad.net Unsubscribe : https://launchpad.net/~yahoo-eng-team More help : https://help.launchpad.net/ListHelp
