<p class="MsoPlainText" style="margin-left:10.5pt;mso-para-margin-left:1.0gd"><span lang="EN-US">My usecase follows:<o:p></o:p></span></p>
<p class="MsoPlainText" style="margin-left:10.5pt;mso-para-margin-left:1.0gd"><span lang="EN-US">1. create two vms A and B by using the ports that have been created.<o:p></o:p></span></p>
<p class="MsoPlainText" style="margin-left:10.5pt;mso-para-margin-left:1.0gd"><span lang="EN-US">2. vm A can ping vm B

<p class="MsoPlainText" style="margin-left:10.5pt;mso-para-margin-left:1.0gd"><span lang="EN-US">3. Delete one port of A or B<o:p></o:p></span></p>
<p class="MsoPlainText" style="margin-left:10.5pt;mso-para-margin-left:1.0gd"><span lang="EN-US">4. vm A can still ping vm B<o:p></o:p></span></p>
<p class="MsoPlainText" style="margin-left:10.5pt;mso-para-margin-left:1.0gd"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoPlainText" style="margin-left:10.5pt;mso-para-margin-left:1.0gd"><span lang="EN-US">IMO, ping should not be ok when vm's port have been deleted.

<p class="MsoPlainText" style="margin-left:10.5pt;mso-para-margin-left:1.0gd"><span lang="EN-US">1. do more restriction in def prevent_l3_port_deletion(self, context, port_id), we should not allow to delete the ports in use.<o:p></o:p></span></p>
<p class="MsoPlainText" style="margin-left:10.5pt;mso-para-margin-left:1.0gd"><span lang="EN-US">2.permit to delete the port but notify ovs-agent to unbind the port.<o:p></o:p></span></p>
