路由器所有接口状态为down
All the router's interfaces status is down
我创建了一个路由器，并在其中为路由器创建了一个接口：
可是你看，状态都是Down，怎么调试界面？为什么都下线了？

在/var/log/neutron/server.log中，我使用cat server.log | grep router，得到以下信息：

因为你的ports管理状态都up了，所以可能有以下几种原因。
- 对端宕机。
- 您的接口上没有电缆。
最后，我发现在我的/etc/neutron/plugins/ml2/ml2_conf.ini配置文件中，我没有配置ml2 type_drivers和mechanism_drivers。所以我配置它们：
# openstack-config --set /etc/neutron/plugins/ml2/ml2_conf.ini ml2 type_drivers flat,vlan,vxlan
# openstack-config --set /etc/neutron/plugins/ml2/ml2_conf.ini ml2 mechanism_drivers linuxbridge,l2population
并重启中子服务器：
systemctl restart neutron-server.service
systemctl restart neutron-l3-agent.service
现在，它工作正常。
