POINT-TO-POINT PROTOCOL FIELD ASSIGNMENTS

PPP DLL PROTOCOL NUMBERS

The Point-to-Point Protocol (PPP) Data Link Layer [146,147,175] contains a 16
bit Protocol field to identify the encapsulated protocol. The Protocol field is
consistent with the ISO 3309 (HDLC) extension mechanism for Address fields.
All Protocols MUST be assigned such that the least significant bit of the most
significant octet equals "0", and the least significant bit of the least significant
octet equals "1".
