Design for overlapping (duplicate) IP networks

Together, the IP Manager and the Global Manager allow service providers who offer managed IP network services to centrally manage the private IP networks of customers who use identically-numbered IP address spaces. Enterprise users facing similar issues due to acquisitions of new networks can also use this ability. Appendix D, “Managing Overlapping IP Networks,” provides more information about managing overlapping IP addresses.

IP tag filters enable the IP Manager to model overlapping IPv4 addresses. The VMware Smart Assurance IP Manager Concepts Guide provides more information about the IP tagging feature and IP tag filters.

Note:

This functionality is needed with the IPv4 protocol. The IPv6 protocol avoids duplicate IP addresses.
