Configuring the VLAN range to be used for the networks
In order to use VLAN as the network type, Neutron requires a range of VLAN identifiers. Each OpenStack Network will be associated with a unique VLAN identifier. This recipe shows you how to configure this range of VLAN IDs.
Getting ready
The valid range for a VLAN ID is 1-4095. However, based on your OpenStack environment and the physical network, it is possible to use a subset of this range.
How to do it…
Configuring the VLAN ID range is a setting in the plugin configuration file. The following steps will show you how to set this range:
- With the appropriate credentials, SSH into the node where the Neutron server is running.
- Open the Neutron ML2 plugin configuration file using your desired editor. For example, the command for vi editor will be as follows:
openstack@controller:~$ sudo vi /etc/neutron/plugins/ml2/ml2_conf.ini - In the
[ml2_type_vlan]section of the file, configure the VLAN range:[ml2_type_vlan] ... network_vlan_ranges ...
