Yamaha Audioversity Rivage Pm Series Network Setup Manual page 23

To connect two or more physically separate Dante networks using the AUTO IP setting, use
a DHCP server to assign IP addresses in different subnets (network addresses) to each
network.
Make sure that the IP address specified for the Dante device IP address and the SLOT IP
are in the same subnet.
As shown in the following example, two or more Dante networks cannot be
used if they all use link-local addresses or their IP addresses are in the same
subnet.
