Neutron 설정 확인

OVS / OVN 구별

컨트롤러 노드에서 ovn_metadata_agent, ovn_controller 데몬이 존재하면 OVN
컨테이너 방식인 경우 podman ps -a |grep Up |grep ovn 명령어로 확인 가능하다. 

[root@overcloud-controller-0 ~]# podman ps -a |grep Up |grep ovn

DVR mode 확인

neutron_api 서비스의 ml2_conf.ini 내용에 distributed_floating_ip 값을 확인한다.

컨테이너 기반인경우 

[root@overcloud-controller-0 ~]# podman exec -it neutron_api bash
[neutron@overcloud-controller-0 /]$ cat /etc/neutron/plugins/ml2/ml2_conf.ini
