I react to this point.

I'm reading again this page
http://docs.ceph.com/docs/next/rados/configuration/network-config-ref
and especially this point:
http://docs.ceph.com/docs/next/rados/configuration/network-config-ref/#ceph-daemons
where I can read:
"Ceph has one network configuration requirement that applies to all daemons: the
Ceph configuration file MUST specify the host for each daemon. Ceph also requires
^^^^^^^^^^^^^^^^^^
that a Ceph configuration file specify the monitor IP address and its port."
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
So if I understand well, a monitor daemon is bound to only one IP.
So I'm a little doubtfully about the possibility of having monitors
which are bound to 2 different addresses and therefore to have 2
different public networks (unless to use routing etc).
