AKA Network Layer Protocol Messages or RPDU (Routing PDU)
This PDU is the Network Layer equivalent of the Application Layer APDU. The Network Layer message and the NPCI make up the NPDU. The NPCI and NPDU are forever getting confused, so we try and be very careful with our terminology. In the search for the equivalent of APDU for the "Network Layer PDU" we reject NPDU as already used. NLPDU does not make us happy, nor is NAPDU appropriate (confusing vs APDU). So in our terminology we use RPDU (Routing PDU, since this is what this PDU is all about anyway...
