We discussed the theoretical knowledge of VXLAN and completed the relevant configuration in ML2.Today you will create vxlan100_net through the Web UI and observe the changes in the node network structure.Open Menu Admin--Networks, click the "Create Network" buttonThe Create page is displayed.Provider Network Type Select "VXLAN" Segmentation ID is VNI, set to 100Click "Create Network" to create a successful vxlan100.Click on the vxlan100 link, go to the Network Configuration page, there is no sub

In the previous section, we have configured and tested LBaaS, and today we focus on how Neutron uses Haproxy to achieve a balanced balance.Running IP netns on the control node, we found that Neutron created a new namespace qlbaas-xxx.The namespace corresponds to the pool "Web servers" we created. Its naming format is qlbaas-You can view its settings through IP a.The VIP 172.16.100.11 is already configured on the namespace interface. The corresponding configuration of the interface can also be fo

) cannot have two VLAN sub-devices of the same ID, so there is no possibility of data exchange. Linux Bridge is designed for switching functions. The sub-devices of the same VLAN are mounted on a Bridge, and data can be exchanged between devices. In summary, Linux Bridge plus VLAN emulates the real-world two-layer switch at the functional level.The eth0 is equivalent to the trunk port on the virtual switch, allowing VLAN10 and vlan20 data to be viewed through eth0.10,vent0 and Brvlan10 both V

The following is the architecture of the Cinder Driver:We can see in the/opt/stack/cinder/cinder/volume/drivers/directory the Driver of the OpenStack source code that has come with a lot of volume provider:The storage node configures the driver used with the Volume_driver option in the configuration file/etc/cinder/cinder.conf:Here LVM is the volume provider we use.periodically report the status of compute nodes to OpenStackI

. VM2 is located in another local network, VM2 cannot communicate with VM0 and VM1 because Brqxxxx and brqyyyy are not connected. Next we will implement the local network step-by-step.enable local network in the ML2 configurationMake sure that ML2 has loaded the local type driver before you create the local network. The ML2 configuration file is located in/etc/neutron/plugins/ml2/ml2_conf.ini.Type_drivers tells ML2 to load all 5 types of netw

abstracted different driver, but the underlying implementation is definitely a difference.So, let's figure out what's changed in the underlying network.Open the shell terminal of the control node and use Ovs-vsctl Show to view the status of the current open vSwitch.You can see that Neutron automatically created port "Tap7970bdcd-f2" on the Br-int Bridge.It is known from the name that the port corresponds to the DHCP interface of local_net.Like Linux bridge driver, DHCP devices are also placed i

Although the external network is an existing network, we still need to define the objects of the external network in Neutron so that router knows how to connect the tenant network to the external network.In the previous section we have configured the ML2 for creating the external network, and this section will create the ext_net through the UI.Go to the Admin-Networks menu and click on the "Create Network" button.The Create page is displayed.Provider network Type Select "Flat" Physical network t

before we created the vlan100 and deployed the instance, today we will continue creating a second VLAN network "vlan101". The subnet IP address is 172.16.101.0/24.what has changed in the underlying networkNeutron automatically creates the vlan101 corresponding bridge Brq1d7040b8-01,vlan interface eth1.101, as well as the DHCP tap device tap5b1a2247-32. Eth1.101 and tap5b1a2247-32 are already connected to Brq1d7040b8-01,vlan 101 's two-layer network ready.Now, the network structure is as follows:

In the previous section we created "Flat_net", which will deploy instance and verify connectivity in this network.Launch the new instance "CIRROS-VM1", select Network Falt_net.The IP assigned to the CIRROS-VM1 is 172.16.1.103.The CIRROS-VM1 is schedule to the control node, the corresponding tap device is TAPC1875C7F-CB, and is already connected to bridge.The structure of the current flat_net is as follows:Continue to launch the instance cirros-vm2 in the same way, assigning the IP to 172.16.1.10
