In communication networks, when new equipment is inserted, in order to communicate with its neighbors it has to be preconfigured or to have the capability to auto configure itself. The paper proposes a protocol implementation as a possible approach to verify and manage the default configuration of two connected network elements (nodes or end devices). The protocol could be used in various scenarios, if the initial configuration was done by a human operator or if it was automatically generated. The protocol focuses on the communication between neighbors and is independent of the mechanism used for initial configuration of each equipment.
