Openstack 中的router创建，floatingip绑定
来源：互联网 发布：网络安全设备巡检流程 编辑：程序博客网 时间：2024/06/06 09:14
网络环境
管理网络：eth0 10.14.0.0/22
数据网络: eth1 vlan105 192.168.105.0/24 ,vlan108 192.168.108.0/24
想要做的事:
1.连通vlan105和vlan108
2.使vlan108可以ping通管理网络10.14.0.0/22
3. 为vlan108下的vm绑定floatingip
1.连通vlan105和vlan108
创建router

2. 使vlan108可以ping通管理网络10.14.0.0/22
需要创建一个外部flat网络10.14.0.0/24 public01
由于public01是flat网络，vlan108是vlan网络，所以需要配置ML2 插件来支持同时使用多种二层网络技术
[root@controller ~]# cat /etc/neutron/plugins/ml2/ml2_conf.ini[ml2]# type_drivers = local,flat,vlan,gre,vxlan# Example: type_drivers = flat,vlan,gre,vxlan#type_drivers = vlantype_drivers = local,flat,vlan,gre,vxlan# (ListOpt) Ordered list of network_types to allocate as tenant# Example: tenant_network_types = vlan,gre,vxlantenant_network_types = vlan,gre,flat,vxlan
创建public01及其子网：
