<div dir="ltr"><div><div>Dear folks</div><div><br></div><div>I have met a problem when implement IPAM driver, ML2 doesn't call remove_subnet function of ipam driver because ML2 doesn't use delete_subnet function of NeutronDbPluginV2</div><div><br></div><div>Now I workaround by using "SUBNET BEFORE_DELETE" event to notify external IPAM that subnet will be deleted, but I think it's not a good solution. According to my understanding this event should be used for checking subnet is in-used or not. I think ML2 should call IPAM driver for this situation or provide additional "SUBNET AFTER_DELETE" event</div><div><br></div><div>Thanks,</div><div>Thanh</div><br>Email:<a href="mailto:legiangthanh@gmail.com" target="_blank"> legiangthan@gmail.com</a><br></div>
