    This network interface can be, for example, a dedicated physical network interface, a VLAN, or a virtual function on an {abbr}`SR-IOV (Single root I/O virtualization)`-capable network interface.
    It serves as the dedicated network interface for MicroCloud and is used for multicast discovery (during setup) and all internal traffic between the MicroCloud, OVN, and Ceph members.
+   The address selected for internal traffic is also advertised by LXD for each cluster member, so it should be reachable by users accessing LXD.
