hi: i use openstack victoria ovn DVR to provide vpc network，and use octavia to provide LB。
At first(20210704), my LB worked fine，and the nbctl show info is:
(py3env) [root@control01 ~]# openstack port show

...
and now the nbctl show info is:
router 0a38aa37-6b88-4871-add0-dee277c0e54f
(neutron-18f83463-1f11-4905-ab44-92fd9364c8d4) (aka cn-shanghai-on-prem-router)

type: "snat"
as you can see, 10.120.25.133 : 10.118.0.0/19 its duplicate
thanks for your help
