Abstract: A system for remote management of private networks having duplicate network addresses is provided which consists of a plurality of managed customer networks (16) within a customer domain (12). The managed customer networks (16) within the customer domain (12) are linked to a level one manager (34) and have unique network addresses. The managed customer networks (16) within the customer domain (12) which have duplicate network addresses are assigned to different level one managers. Errors occurring in the managed customer networks are sent to a level one manager (34) which generates an error message uniquely identifying the node or interface link experiencing the error. This error message is forwarded to a level two manager (40) which then routes the error message to an appropriate operator console (42) where the error is diagnosed and corrected.
