They can be added in VLAN-based environments where networks are expensive to increase the number of hosts allowed on the network later.</div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Mar 31, 2015 at 7:43 AM, <span dir="ltr"><<a href="mailto:sparkofwisdom.cloud@gmail.com" target="_blank">sparkofwisdom.cloud@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div style="font-family:sans-serif;font-size:16px"><div>

Do we have clarity on this question? I think it will be more important for IPv6 enabled port…Any guidance from the Neutron Core? </p>

Hello, Oleg Bondarev.</p>
<p style="margin:0px;padding:0px">
</p>
<p style="margin:0px;padding:0px">
Sir, I could not find out any merit of multi subnets on one network, except the following one.</p>
<p style="margin:0px;padding:0px">
- Migrate IPv4 to IPv6, so we need both subnet range on one network.</p>
<p style="margin:0px;padding:0px">
So I don't know very much the nesessery of max_fied_ips_per_port parameter.</p>
<p style="margin:0px;padding:0px">
All I know is only DB module and opencontrail plugin are using this parameter for validate.</p>
<p style="margin:0px;padding:0px">
Do we have any usages about this issue, please?</p>
<p style="margin:0px;padding:0px">
I appreciate a lot of your help.</p>
