System configuration for multiple domains
By splitting Vnet/IP stations in a system according to the operation scope and maintenance unit,
you can enable optimal management of messages in each domain. To connect the split domains,
use a layer 3 switch for each bus 1 and bus 2 of the split domains.
The following figure shows an example of how to split a Vnet/IP domain. The IP address for each
port in the recommended layer 3 switch is set by default. Therefore, to set up a system, you only
have to connect to the layer 2 switches in each domain and to those ports with the same number
as the domain number.
