Thanks

Seeing these Geneve tunnel overlay network got created for each chassis , even though no project based network created.

Is this getting created as part of config from openstack neutron config ? 

Can you please on this ?

Hello.

 In my environment, users are not allowed to create networks (this is enforced using network quotas), and provider networks can only be created with admin permissions.

Hello Team

We are using ML2+OVN based on Provider Network with Vlan ( no tenant network ) , for hypervisor to hypervisor traffic we are using physical L2 network.  We are not using geneve tunnel anymore. 

How to disable these tunnel in OVN deployment? Is this expected?
