When using AVR10D style S3 V net routers, you can set either Vnet/IP or V net as the upper
domain. However, you must set Vnet/IP as the upper domain for AVR10D style S2 V net routers.
You can connect Vnet/IP and V net in an alternating series by using the AVR10D style S3 V net
router. In this case, you can connect only up to two V net routers where V net is set as the upper
domain. This limitation does not include the number of V net routers where Vnet/IP is set as the
upper domain.

IMPORTANT
You must check the communication bandwidth if you are connecting Vnet/IP domains to Vnet
domains. Estimate the communication bandwidth used by V net, including the volume of
communication between Vnet/IP domains that passes through V net.
TIP
Upgrade all Vnet/IP stations to Vnet/IP rmware revision 16 or later to enable Vnet/IP domains to communicate
with each other through V net domains.
