Accommodating a Maximum Transit Unit/Maximum Receive Unit Greater Than 1492 in the Point-to-Point Protocol over Ethernet
RFC 4638, “Accommodating a Maximum Transit Unit/Maximum Receive Unit Greater Than 1492 in the Point-to-Point Protocol over Ethernet”, is an Informational document published in September 2006 by P. Arberg, D. Kourkouzelis, M. Duckett, T. Anschutz, J. Moisand. The canonical text is published by the RFC Editor.
Abstract
The Point-to-Point Protocol over Ethernet (PPPoE), as described in RFC 2516, mandates a maximum negotiated Maximum Receive Unit (MRU) of 1492. This document outlines a solution that relaxes this restriction and allows a maximum negotiated MRU greater than 1492 to minimize fragmentation in next-generation broadband networks. This memo provides information for the Internet community.
