Open Stack

From my understanding, it depends on the scenario that how you deployed the OpenStack services. If you did not enable DVR in the configuration, and did not deploy the L3 agent on the compute nodes, then the DVR service/function is not enabled.

Does that depend on DVR to function?

As I understand it, OpenStack Kilo uses DVR by default when you use KVM for your compute.
But with vCenter for compute, I have a hunch that I may need NSX to make this work. (Because there's not distributed virtual router for the ovsvapp nodes.)

But, again, I could be wrong on this.

Hi,


If you would have both VLAN and VxLAN types of provider networks, it is possible to accomplish that.


First of all, you need to provide the right configuration in the file of "openvswitch_agent.ini" and "ml2_conf.ini". Then with two NICs (ports), connect them to the different bridges (one for VLAN (br-vlan) and the other for VxLAN (br-tun)), respectively. At this stage, you should have two types of provider networks, one for VLAN and the other for VxLAN.


Br,
Chao

I want to have VLAN provider networks for some customers.

I currently have my cloud configured for VxLAN, and I'm not able to create a VLAN provider network.

 Do you mean for tenant networks, or for provider networks?
 
 I believe it's possible for provider networks, but not for tenant. [1]

 Out of interest, why do the legacy customers need VLAN specifically?

 I'm afraid I have no idea about this dimension!
