In addition to configuring a router to route packets between each IP Manager and its management domain, you need to create an IP tag filter for one of the Domain Managers so that the IP Manager can distinguish between the overlapping addresses that are used by the two locally distinct groups of devices in the two IP management domains.

Upon creating an IP tag filter for one of the IP Managers, that IP Manager will add a distinguishing tag to the names of the IP objects that represent the IP addresses in its management domain, while the other IP Manager will not.
