-Nodes will typically have an additional NIC used by the baseboard management controllers (BMCs). These BMCs must be accessible from the provisioner node.
+Nodes typically have an additional NIC used by the baseboard management controllers (BMCs). These BMCs must be accessible from the provisioner node.
 
 Each node must be accessible via out-of-band management. When using an out-of-band management network, the provisioner node requires access to the out-of-band management network for a successful {product-title} installation.
 
-The out-of-band management setup is out of scope for this document. We recommend setting up a separate management network for out-of-band management. However, using the provisioning network or the baremetal network are valid options.

+====
+The bootstrap VM features a maximum of two network interfaces. If you configure a separate management network for out-of-band management, and you are using a provisioning network, the bootstrap VM requires routing access to the management network through one of the network interfaces. In this scenario, the bootstrap VM can then access three networks:
+
+* the bare metal network
+* the provisioning network
+* the management network routed through one of the network interfaces
