注意 net1 中的 subnets values 部分 3066c397-bccf-4473-8a94-72b09a97a70a 显示为 terry_pri_net1 中的 ID 值
如果使用 vlan 网络
创建网络时候需要先把 vlan tag 进行定义, 例如
neutron net-create --variable segmentation_id=2030 --tenant-id 36c8fbaa-f178-4fd1-a614-2e8276ddd63f DMZ7_NET
子网创建参考
neutron subnet-create --name DMZ7_SUBNET --allocation-pool start=10.199.30.10,end=10.199.30.254 --no-gateway --host-route destination=0.0.0.0/0,nexthop=10.199.30.1 --dns-nameserver 10.189.208.21 --dns-nameserver 10.189.208.22 --ip-version 4 DMZ7_NET 10.199.30.0/24
创建网络后 ,需要激活 dhcp agent
# neutron agent-list | grep DHCP
