In some complex environments, you might need to create separate configuration files for multiple domains.
A single BOFM configuration corresponds to a single BOFM domain, in which duplicated addresses are not allowed. In general, unless you have a special reason to do so, it is best practice to have one configuration file for the entire domain. This way the AMM verifies that there are no address duplications when you modify the BOFM configuration.
However, in a more complex environment, it may be convenient to have multiple domains, where the same addresses can exist in different domains. In this case, you can generate a separate configuration file for each domain.
