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