Open Stack

Guys,

I now how to reproduce this and I filled a BUG report about it, here:

https://bugs.launchpad.net/neutron/+bug/1322945

It seems that a regular user can breaks the Neutron L3 Router, by "Adding a
Interface" to its Namespace Router, that is attached to a IPv6 private
subnet, it also breaks an "admin" External Network... Seems to be serious
(I think).

Regards,
Thiago
