I have a complete openstack KILO version installed and working perfectly okay using GRE.

My Network+Compute+Control nodes have are configured to

tenant_network_type =vlan, gre

Is there any way to convert the GRE to VLAN.

like what modifications are required for vlan enablement.

Delete all the existing networks & ports.

Recreate & DBsync neutron DB (You already have both VLAN & GRE in type drivers so neutron DB recreation and Sync may not required)

Do the below configurations in /etc/neutron/plugins/ml2/ml2_conf.ini file.


tenant_network_types = vlan
type_drivers = local,flat,vlan,gre,vxlan
mechanism_drivers = openvswitch



network_vlan_ranges = physnet2:1000:2999




enable_security_group = True
enable_ipset = True
firewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver

local_ip =
tenant_network_type = vlan
integration_bridge = br-int
network_vlan_ranges = physnet2:1000:2999
bridge_mappings = physnet2:br-em2

hi Vinoth,

thanks for your reply.

Are these changes supposed to be implemented on both Network + compute nodes ...or something else is needed to change on the Controller Side as well. Please suggest. Thanks again for your response.

or call it be a change on the network only..compute only or controller only?

This configuration changes need to be done in both network & compute node with respective IP address of tunnel network.
