Configure the Neutron OVS plug-in for GRE tunneling

Configure the OVS plug-in to use GRE tunneling, the br-int integration bridge, the br-tun tunneling bridge, and a local IP for the DATA_INTERFACE tunnel IP. Edit the /etc/neutron/plugins/openvswitch/ovs_neutron_plugin.ini file:

[ovs]
tenant_network_type = gre
tunnel_id_ranges = 1:1000
enable_tunneling = True
integration_bridge = br-int
tunnel_bridge = br-tun
local_ip = DATA_INTERFACE_IP

Return to the general OVS instructions.
