Re: hwvtep high level control flow

Hi Daya/Sam,


              I have the few queries on the document.


1. There are 3 ways VXLAN can be established,

i.         VXLAN between OVS switches controlled by openstack and ODL.

a.       This is already supported in software VTEP.

ii.       VXLAN between hardware gateway and OVS switch controlled by openstack and ODL.

a.       This will be supported in hardware VTEP project.

iii.     VXLAN between 2 hardware gateways connected to bare metal servers.

a.       Are we planning to support VXLAN between hardware gateway. From the control flow document, I could infer we don’t support this kind of a setup.


        2. How does ODL react when the switch initiates the OVSDB  connection using ptcp?

I am asking this because the switches will have CLI’s to do these configurations and it is possible the switch can initiate the OVSDB connection. As per the L2GW slide, the openstack initiates the hardware gateway creation.


If we are planning to support this case, will the openstack be informed about the hardware gateway creation?

Subject: [ovsdb-dev] hwvtep high level control flow



here's a first draft of how the control flow to incorporate hwvtep into netvirt.

sam, unfortunately, out of force of habit i started in ppt, and when i copied it to google, it got pasted as a picture.

attaching to this email also, i can incorporate comments and update, or re-do it so its editable, when i have some more time.
