Hi all!
Thank you for your replies.
The VLAN range I posted on my email was a typo. The command I used had the
correct range 1000:1009. The network templates were configured according to
my physical network.
I followed Marius suggestion and used the following command to deploy the
overcloud stack:
openstack overcloud deploy --control-scale 3 --compute-scale 3
--libvirt-type kvm --ntp-server pool.ntp.org --templates ~/the-cloud/ -e
~/the-cloud/environments/puppet-pacemaker.yaml -e
~/the-cloud/environments/network-isolation.yaml -e
~/the-cloud/environments/net-single-nic-with-vlans.yaml -e
~/the-cloud/environments/network-environment.yaml --control-flavor
controller --compute-flavor compute --neutron-network-type vlan
--neutron-bridge-mappings datacentre:br-ex --neutron-network-vlan-ranges
datacentre:1000:1009 --neutron-tunnel-types vlan
The overcloud stack was deployed in VLAN mode without the GRE-tunnels.
However, it doesn't work correctly because the neutron-openvswitch-agent is
unable to start as it doesn't recognize "vlan" as a tunnel mode.
I captured the followinfg error in /var/log/neutron/openvswitch-agent.log

So the --neutron-tunnel-types vlan command allows the deployment to pass
the CLI bug but creates a problem in neutron configuration.
Do you have any other suggestions?
Thank you very much!
