Every router manager installed in the system has a registry key created under the Router key. The DLLPath variable specifies the location of the DLL that corresponds to the router manager and the ProtocolID variable specifies the protocol family identifier for the router manager.

The Interfaces key is populated with the interfaces that have been added to the local system from the Router configuration. Each interface has an associated Type (Internal, Dedicated, or Dynamic) and subkeys for each router manager (IP and IPX, for example).
