We recommend using both a public (front-end) network and a cluster (back-end)
network so that you can better meet the capacity requirements of object
replication. Another advantage is that you can run a cluster network such that

attacks. When OSDs peer and check heartbeats, they use the cluster (back-end)
network when it's available. See `Monitor/OSD Interaction`_ for details.
