A dictionary of networks to configure on the nodes. Three networks are required by all PVC clusters, though additional networks may be configured here as well. A dictionary of networks to configure on the nodes.
The three required networks are: `upstream`, `cluster`, `storage`. The key will be used to "name" the interface file under `/etc/network/interfaces.d`, but otherwise the `device` is the real name of the device (e.g. `iface [device] inet ...`.
The three required networks are: `upstream`, `cluster`, `storage`. If `storage` is configured identically to `cluster`, the two networks will be collapsed into one; for details on this, please see the [documentation about the storage network](/cluster-architecture#storage--connecting-ceph-osd-with-each-other).
Additional networks can also be specified here to automate their configuration. In the above example, a "bondU" interface is configured, which the remaining required networks use as their `raw_device`.
