A DvR isolated domain separates the DvR Controller from the DvR backbone in a Fabric Network. Configure an isolated Controller for the following benefits:
to create DvR-enabled networks without backbone size limitations
to prevent flooding from a backbone with many entries
to improve the performance of less powerful devices as DvR Controllers
