Hello Gianluca, Please check on the engine what hosts are registered on ovn-north: #ovn-sbctl show
For each registered host you should see something like: Chassis "69b6b2a6-5afb-4908-8d66-c648cbe09ba8" hostname: "f43" Encap geneve ip: "192.168.120.43" .... I would assume you have some unwanted entries there (10.4.168.74) To get rid of this please use: # ovn-sbctl chassis-del <chassis id> // for example: ovn-sbctl chassis-del 69b6b2a6-5afb-4908-8d66-c648cbe09ba8 Please let me know if this helps. Note also that you would have to runplug/plug any vnics on any vm's you have on those two hosts.
