文档版本：1.0
本操作分别在三个节点上完成
一. 配置控制节点
root@controller:~(keystone)# vim /etc/neutron/plugins/ml2/ml2_conf.ini
# 第130行：添加网络类型
tenant_network_types = vxlan
# 第181行：添加
flat_networks = physnet1
# 第235行：添加
vni_ranges = 1:1000
root@controller:~(keystone)# systemctl restart neutron-server
二. 配置网络节点
root@network:~# vim /etc/neutron/plugins/ml2/ml2_conf.ini
# 第130行：添加网络类型
tenant_network_types = vxlan
# 第181行：添加
flat_networks = physnet1
# 第235行：添加
vni_ranges = 1:1000
root@network:~# vim /etc/neutron/plugins/ml2/linuxbridge_agent.ini
# 第118行：添加
[agent]
prevent_arp_spoofing = True
# 第147行：添加
[linux_bridge]
physical_interface_mappings = physnet1:ens3
# 第201行：添加
[vxlan]
enable_vxlan = True
l2_population = True
l2_population = True
root@network:~# vim /etc/neutron/dhcp_agent.ini
# 第63行：添加
dnsmasq_config_file = /etc/neutron/dnsmasq-neutron.conf
root@network:~# vim /etc/neutron/dnsmasq-neutron.conf
# 这是一个新文件，添加以下内容
dhcp-option-force=26,1450
root@network:~# for service in l3-agent dhcp-agent metadata-agent linuxbridge-agent; do
systemctl restart neutron-$service
done
systemctl restart neutron-$service
done
三. 配置计算节点
root@compute:~# vim /etc/neutron/plugins/ml2/ml2_conf.ini
# 第130行：添加网络类型
tenant_network_types = vxlan
# 第181行：添加
flat_networks = physnet1
# 第235行：添加
vni_ranges = 1:1000
root@compute:~# vim /etc/neutron/plugins/ml2/linuxbridge_agent.ini
# 第118行：添加
[agent]
prevent_arp_spoofing = True
# 第201行：添加
[vxlan]
enable_vxlan = True
l2_population = True
l2_population = True
root@compute# systemctl restart neutron-linuxbridge-agent
四. 创建网络及路由（控制节点上完成）
[1] 创建虚拟路由
root@controller:~(keystone)# openstack router create router_01

# 连接外部网络到路由
root@controller:~(keystone)# openstack router set router_01 --external-gateway ext_net
[3] 创建内部网络
