I'm trying to integrate odl in openstack but i cant get floating ip and connectivity external network to work. 192.168.0.1/24 is provider network 10.0.0.0/24 is management net and 10.0.1.0/24 is overlay network but i dont think that is needed because for now it is only 1 compute nod DHCP sometime does not work too, i need to reset openvswitch service and odl controller serveral times, delete networks to get it working. External network is not working at all compute node /etc/network/interfaces

# The primary network interface
auto ens3
iface ens3 inet dhcp
#management network
auto ens8
iface ens8 inet static
        address 10.0.0.31
        netmask 255.255.255.0

#provider network
auto ens9
iface ens9 inet manual
        up ip link set dev $IFACE up
        down ip link set dev $FACE down

#overlay network
auto ens10
iface ens10 inet static
        address 10.0.1.31
        netmask 255.255.255.0
