Hello All, I have deployed OpenStack Yoga using kolla ansible with a single external interface initially. Later we realized that we wanted to use multiple interfaces. I have followed the docs to modify the external interface in the globals.yml file as below. *Before:* *globals.yml* neutron_external_interface: "bond2" *After:* *globals.yml* neutron_external_interface: "bond2,enp6s0f1" neutron_bridge_name: "br-ex,br-ex2" *Command used:* kolla-ansible -i multinode reconfigure --tags "common,horizon,neutron" -vv br-ex2 doesn't show up in the neutron nodes. I also noticed that my neutron-openvswitch-agent is continuously restating in both the neutron nodes. neutron-openvswitch-agent.log says as below 2022-12-15 02:12:35.121 7 INFO neutron.plugins.ml2.drivers.openvswitch.agent.openflow.native.ovs_bridge [-] Bridge br-int has datapath-ID 0000be5c93241c4f 2022-12-15 02:12:36.040 7 INFO neutron.plugins.ml2.drivers.openvswitch.agent.ovs_neutron_agent [-] Mapping physical network physnet1 to bridge br-ex 2022-12-15 02:12:36.041 7 INFO neutron.plugins.ml2.drivers.openvswitch.agent.ovs_neutron_agent [-] Bridge br-ex datapath-id = 0x0000801844eaf971 2022-12-15 02:12:36.057 7 INFO neutron.plugins.ml2.drivers.openvswitch.agent.openflow.native.ovs_bridge [-] Bridge br-ex has datapath-ID 0000801844eaf971 2022-12-15 02:12:36.063 7 INFO neutron.plugins.ml2.drivers.openvswitch.agent.ovs_neutron_agent [-] Mapping physical network physnet2 to bridge br-ex2 2022-12-15 02:12:36.063 7 ERROR neutron.plugins.ml2.drivers.openvswitch.agent.ovs_neutron_agent [-] Bridge br-ex2 for physical network physnet2 does not exist.

How can I resolve both issues? Kindly help.
