Thank you for telling us such a method.

First, I made an OSP5 using packstack with a default answerfile.
and I found neutron is vxlan mode.

Then, we reinstalled the host, and we tried to config the plugin.ini
file, however we did not find br-tun in my host.
How do slove it, create br-tun manually(then what?) or others? any idea?

# 3. With VXLAN tunneling.
# [ovs]
# network_vlan_ranges =
# tenant_network_type = vxlan
# tunnel_type = vxlan
# tunnel_id_ranges = 1:1000
# integration_bridge = br-int
# tunnel_bridge = br-tun
# local_ip = 10.0.0.3
# [agent]
# tunnel_types = vxlan


# ip addr | grep br-int
17: br-int: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN
# ip addr | grep br-tun
