Overlapping IP addresses versus management IP addresses

An overlapping IP address is typically an address on an edge system’s physical interface, not the address — known as a management IP address — bound to the edge system’s SNMP agent. (An edge system is a system at the edge of the managed network environment.) An overlapping IP address is typically unreachable in the sense that no routes exist between the host running the IP Manager and the overlapping IP address.

Note:

A management IP address is the address that the IP Manager uses to discover information about a system and to monitor the system after it is discovered.
