>>> Currently, LBaaS will make internal service calls (clean interface :/)<br>
>>>to create and attach a Neutron port.<br>
>>> The VIP from this port is added to the Loadbalancer object of the Load<br>
>>>balancer configuration and returned to the user.<br>
>>><br>
>>> This creates a bit of a problem if we want to associate a FLIP with the<br>
>>>port and display the FLIP to the user instead of<br>
>>> the ports VIP because the port is currently created and attached in the<br>
>>>plugin and there is no code anywhere to handle the FLIP<br>
>>> association.<br>
>>><br>
>>> To keep this short and to the point:<br>
>>><br>
>>> We need to discuss where and how we want to handle this association. I<br>
>>>have a few questions to start it off.<br>
>>><br>
>>> Do we want to add logic in the plugin to call the FLIP association API?<br>
>>><br>
>>> If we have logic in the plugin should we have configuration that<br>
>>>identifies weather to use/return the FLIP instead the port VIP?<br>
>>><br>
>>> Would we rather have logic for FLIP association in the drivers?<br>
>>><br>
>>> If logic is in the drivers would we still return the port VIP to the<br>
>>>user then later overwrite it with the FLIP?<br>
>>> Or would we have configuration to not return the port VIP initially,<br>
>>>but an additional query would show the associated FLIP.<br>
>>><br>
>>><br>
>>> Is there an internal service call for this, and if so would we use it<br>
>>>instead of API calls?<br>
>>><br>
>>><br>
>>> Theres plenty of other thoughts and questions to be asked and discussed<br>
>>>in regards to FLIP handling,<br>
>>> hopefully this will get us going. I'm certain I may not be completely<br>
>>>understanding this and<br>
>>> is the hopes of this email to clarify any uncertainties.<br>
