As part of openstack-ansible deployment, removed geneve tunnel config as you mentioned, now we have only below on neutron server [ml2] type_drivers = vlan tenant_network_types = vlan mechanism_drivers = ovn Same config for neutron in compute node as well, under ovn external_id external_ids : {hostname=xxxx ovn-bridge-mappings="vlan:br-ex", ovn-cms-options="availability-zones=nova", ovn-remote="tcp:xxxx:6642,tcp:xxxxx:6642", rundir="/var/run/openvswitch", system-id="01a70eda-59bb-4e8b-870d-08eba09abae3"} With above config, we do see below error in ovn-controller & not able to connect to SB DB ovn-controller.log: 2025-04-29T17:38:48.508Z|00012|main|INFO|OVN internal version is : [24.03.2-20.33.0-72.6] 2025-04-29T17:38:55.206Z|00026|chassis|INFO|Need to specify an encap type and ip 2025-04-29T17:38:55.206Z|00027|chassis|INFO|Need to specify an encap type and ip 2025-04-29T17:38:55.206Z|00028|chassis|INFO|Need to specify an encap type and ip can you please share your inputs on this ?
