Hi Aaron!

The BUG report https://bugs.launchpad.net/neutron/+bug/1322945 is about
this problem, I posted there the instructions to reproduce it...

Basically, after attaching a private IPv6 subnet to your L3 Router, it will
break the "External Network" and its "Floating IPs", then, it becomes
impossible to delete that "External Network"... It enters in a "stuck"
state...

Regards,
Thiago
