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 provides more information about the IP tagging feature and IP tag filters.This functionality is needed with the IPv4 protocol. The IPv6 protocol avoids duplicate IP addresses.
