Open Stack

Hi All,

Thanks you, Ageeleshwar, for the response. I changed the ml2 configuration for vlan from 1 to 8. The log and dump are in the following. But, I have a question how the tenant subnet associated with a vlan? I want to have my both tenants with 192.168.2.x and 192.168.3.x subnets to associate vlan2 and vlan3.  How can I do that with vlan?

Thanks,
Mitchell

[ml2]
type_drivers = vlan
tenant_network_types = vlan
mechanism_drivers = openvswitch

[ml2_type_vlan]
network_vlan_ranges = physnet1:1:8

[ovs]
local_ip = 192.168.1.218
bridge_mappings = physnet1:br-eth1
tenant_network_type = vlan
network_vlan_ranges = physnet1:1:8
integration_bridge = br-int

Subject: Re: [Openstack] Change from GRE to vlan

Apart from type_driver, there are many other setting in 'ml2_conf.ini'. Like below

[ml2]

mechanism_drivers=openvswitch

type_drivers=vlan,flat

tenant_network_types=vlan,flat

[ml2_type_flat]
flat_networks=Extnet

[ml2_type_vlan]

network_vlan_ranges=Intnet1:100:200

[ovs]

bridge_mappings=Intnet1:br-eth1, Extnet:br-ex

In above configuration I am using one flat External network 'Extnet' and One vlan network 'Intnet1'.
I would suggest read through the documentation given in the config file. It is a good starting point.
In case you need more info we have created a few blog posts that could be of help.

Do write back if you need any further information.

Thank you,

Hi All,

I have, step by step, followed the OpenStack icehouse installation guide to install control, compute and neutron nodes. They all run fine like OpenStack document describes. There is a GRE tunneling connection described in OpenStack installation guide from compute nodes to a neutron node. We currently plan to change the GRE tunneling connection to vlan, but I don't see the Openstack installation describes detail for setting up vlan.

I can see the type driver need to be changed from gre to vlan in ml2_conf.ini files in all nodes. I also got a HP switch configured vlan trunk ports for each computer and neutron systems to replace the current flat switch in the physical private connection.

Besides the above mentioned ml2_conf.ini change and physical connection change, is there anything else I need to do for setting the vlan connection to get the external/internal nets, subnets and the router to work again to build instances? I am going to do this work very soon and will appreciate advices from your experience.

Thank you,
Mitchell
