本文是配置文档，非说明文档，只讲配置，不讲原理。
controller节点：
网卡信息：ens160 外网网卡 ； ens192 数据网卡
/etc/neutron/plugins/ml2/ml2_conf.ini配置
/etc/neutron/plugins/ml2/ml2_conf.ini的所有配置项
[DEFAULT]
[ml2]
type_drivers = flat,vlan,vxlan
tenant_network_types = vlan

[ml2_type_flat]

/etc/neutron/plugins/ml2/openvswitch_agent.ini
下图是从vxlan模式修改过来的配置。注意enable_tunneling=false
直接配置成vlan模式
/etc/neutron/plugins/ml2/openvswitch_agent.ini
[DEFAULT]
[agent]
tunnel_types = vxlan
vxlan_udp_port =
l2_population = False
prevent_arp_spoofing = False
arp_responder = False
[ovs]
bridge_mappings = external:br-ex,default:br-eth1
local_ip = 10.0.10.150
tunnel_bridge = br-tun
integration_bridge = br-int
tunnel_id_ranges = :
tenant_network_type = vxlan
enable_tunneling = false
tunnel_types = vxlan
[securitygroup]
enable_security_group = False
firewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver
[xenapi]
修改好所有的配置后创建网桥，重启服务。原理见vxlan分析。
ovs-vsctl add-br br-eth1 ovs-vsctl add-port br-eth1 ens192 service neutron-openvswitch-agent restart
compute节点：
网卡信息：ens160 外网网卡；ens192 管理网卡
/etc/neutron/plugins/ml2/ml2_conf.ini
/etc/neutron/plugins/ml2/openvswitch_agent.ini
计算节点同样要创建br-eth1网桥
ovs-vsctl add-br br-eth1 ovs-vsctl add-port br-eth1 ens192 service neutron-openvswitch-agent restart
/etc/neutron/plugins/ml2/openvswitch_agent.ini
