Address duplication in your network may cause Link and Connection Inference to infer incorrect links. The following topics are covered in the sections that follow:

Duplication of IP addresses in your network can cause incorrect results for inference engines that use IP address. You can use the Duplicate IP Address report to determine if you have duplicate addresses.

In the case of overlapping IP addresses, Link and Connection Inference may be configured to perform group-based link inference. For more information, see Group-based inference.

Duplication of MAC addresses in your network can cause incorrect results for the MAC Address Based Forwarding Table engine. You can use the Duplicate MAC Address report to determine if you have duplicate addresses.
