neutron 网络笔记

1、创建两个网络和两个子网：

2、登陆到计算节点和控制节点，查看网桥和namespace状态,记录当前状态：

[[email protected] ~]# ip netns list
qrouter-186e93d4-3f43-4cdc-b013-82e1c43821ad
[[email protected] ~]# ovs-vsctl show
bc77bed4-0060-40de-a634-eff807cc39fd
    Manager "ptcp:6640"
        is_connected: true
    Bridge br-int
        Controller "tcp:172.18.141.193:6633"
            is_connected: true
        Port br-int
            Interface br-int
                type: internal
        Port "qg-b6dc07fe-97"
            Interface "qg-b6dc07fe-97"
                type: internal
        Port "qr-135fb12c-cb"
            Interface "qr-135fb12c-cb"
                type: internal
    ovs_version: "2.9.0"

3、创建两个虚机，分别属于刚才创建的两个网络：

4、查看两个计算节点，br-int下面创建了两个连接到子网的port
Port “tap5be36a13-c7”

[[email protected] ~]# ovs-vsctl show
2802690d-780f-4630-86ff-e1245dfdcbe1
    Manager "ptcp:6640"
        is_connected: true
    Bridge br-int
        Controller "tcp:111.111.111.193:6633"
            is_connected: true
        Port "vxlan1"
            Interface "vxlan1"
                type: vxlan
                options: {key=flow, local_ip="111.111.111.192", remote_ip=flow}
        Port "tap5be36a13-c7"
            Interface "tap5be36a13-c7"
        Port br-int
            Interface br-int
                type: internal
    ovs_version: "2.7.3"

tap03e4addd-60

[[email protected] ~]# ovs-vsctl show
d559eb26-8798-49ea-bb12-4c07e96df27d
        Port "tap03e4addd-60"
            Interface "tap03e4addd-60"
        Port "tapf791b209-84"
            Interface "tapf791b209-84"
        Port "tap9f3d7b2f-10"
            Interface "tap9f3d7b2f-10"
    ovs_version: "2.7.3"

5、进入一个主机，两者互ping 不通
6、创建router，在控制节点上看namespace，会多出一个namespace，如下：

查看网络节点的namespace：
