vlan id maps to the segmentation-id of the network. Later when you create a
subnet under a network the subnet is associated to the
vlan-id(segmentation-id) of its network.
So all you have to do is provide '--provider:segmentation-id' param while
creating network. I am not sure with the exact param name, though it should
be something like what I have mentioned. I do not have access to my
OpenStack, but you can look it up using 'neutron net-create --help'. I am
not sure if the dashboard allows you to do this, so use the cli. Finally
make sure you do this as 'admin' user.
Thank you,
