Hi All, As specified in this link: https://openstack.redhat.com/Neutron_with_existing_external_network network restart takes destroys and recreates br-ex which causes the router's interface in the qrouter-* netns to be deleted, and it won't be recreated without clearing and re-setting the gateway. This means whenever I do network restart I need to recreate external subnet and assign new floating IPs to the existing VMs.Is there a way I can prevent this? Thanks, Priyanka
