Create the First VLAN network "VLAN100"-5 minutes a day to play with OpenStack (94)

In the previous section we enable VLAN network in the ML2 configuration, and today we will create vlan100 and discuss the underlying networking changes.

Open the menu, Admin, Networks, and click on the "Create Network" button.

The Create page is displayed.

Provider Network Type Select "VLAN". Physical Network fill in "Default" and must be consistent with Ml2_conf.ini network_vlan_ranges. The segmentation ID, which is the VLAN ID, is set to 100.

Click "Create Network" to create a successful vlan100.

Click on the vlan100 link, go to the Network Configuration page, there is no subnet, click the "Create Subnet" button.

The Subnet_172_16_100_0,ip address is 172.16.100.0/24.

what has changed in the underlying network

Perform brctl show on the control node to view the current network structure.

Neutron automatically new three devices: 1. Vlan100 the corresponding bridge brq3fcfdb98-9d. 2. VLAN interface eth1.100. 3. DHCP tap device tap1180bbe8-06.

Eth1.100 and Tap19a0ed3d-fe have been connected to Brq3fcfdb98-9d,vlan 100 's two-layer network ready, at this time vlan100 structure:

The next section deploys instance to vlan100 and continues to explore changes in the underlying network structure.
