The actual Layer 4 port used may vary between drivers (linuxbridge vs OVS), but that would either be hard-coded or defined within a configuration file.

Subject: [Openstack] [openstack-dev][openstack] API to get tunnel port connect to other host

Is there any neutron API, which returns the tunnel port details connected to other host ?
For eg. I have Host-A and Host-B. Is there a way to know what is the tunnel-port on Host-A which connects Host-B ?
Can't use OVS commands directly.
