Please just remember that today many high level features like LBaaSv2 + Octavia is not working [1] when you’re using DVR + L3/HA.
<div class="">Designing that cloud you need to remember that for today there is a huge chance that you will not be able to use anything except base L2/L3 connectivity from networking perspective.<br class="">

<div dir="ltr" class="">Thanks for your response. We are assuming that if we use DVR with L3 HA there is no need of network segment/cluster. Could you please share your thoughts on this.</div>

</span>I've asked this question in operator sessions at the Summits and at<br class="">
the NYC operators mid-cycle with not much response. In the Neutron<br class="">
feedback session last week, there was one person that said he was<br class="">
running DVR, but that it had architectural issues with IPv6. I got<br class="">
the impression that his environment was much smaller than what you're<br class="">
considering.<br class="">
