Comment 1 for bug 1838403

Strange, when a port is deleted the floating IP will be dis-associated and two events notifications should happen according to the code in disassociate_floatingips(). Was the port associated with the VM deleted? I haven't tried that locally yet.

Regarding the second issue, trying to clear the gateway when a router has an associated floating IP should generate an error. I just tried this using horizon on got this:

"Error: Unable to clear gateway for router router1. Most possible reason is because the gateway is required by one or more floating IPs"

Can you confirm the version of Neutron you're running? Thanks
