Comment 2 for bug 1689683

Also from 1654144 - Per Bruno Carvalho (brunowcs):

juju version
2.2-beta4-xenial-amd64

21:23:48 DEBUG juju.provider.openstack provider.go:1133 allocating public IP address for openstack node
21:23:49 ERROR juju.cmd.juju.commands bootstrap.go:491 failed to bootstrap model: cannot start bootstrap instance: cannot allocate a public IP as needed: could not find an external network in availablity zone

----

I am using nuage with neutron plugin for SDN I believe the compatibility is in the form of my implementation, since my external network is configured without AZ

# openstack network show 42f7deed-1410-408e-ad4b-c1394ca47b40(MY EXTERNAL ID)
....
Availability_zones | None
....

I will check the possibility of updating external networks already created for AZ, using the nuage neutron plugin.
