<p class="MsoNormal"><span style="mso-bookmark:_MailOriginalBody">> Any suggestion? <o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-bookmark:_MailOriginalBody"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="mso-bookmark:_MailOriginalBody">What do you mean by “clean”?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-bookmark:_MailOriginalBody"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="mso-bookmark:_MailOriginalBody">Contrail will ignore all information in the neutron db.<br>
Any incoming neutron api call will be translated to a contrail-api call.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-bookmark:_MailOriginalBody">Contrail itself does not use the Mysql database but has its own (Cassandra) databases<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-bookmark:_MailOriginalBody">So any router/subnet/network/interface etc object that currently exists in the neutron/mysql database is ignored.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-bookmark:_MailOriginalBody">That basically means any object that is using “stock-neutron” will break since it will need to be re-created on contrail.<o:p></o:p></span></p>
