Furthermore, this document presents some requirements for registering new values and making the processing of MPLS packets easier and more robust. The relationship between the IANA "Post-Stack First Nibble" registry and the "IP Version Numbers" registry (RFC 2780) is described in this document. This document updates RFC 4928 by deprecating the heuristic method for identifying the type of packet encapsulated in MPLS.', set pages to 15, set standardization level to Proposed Standard, added RFC published event at 2025-07-10, created updates relation between RFC 9790 and RFC 4928) |
