Accommodating a Maximum Transit Unit/Maximum Receive Unit (MTU/MRU) Greater Than 1492 in the Point-to-Point Protocol over Ethernet (PPPoE)

Status of This Memo This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited. As of this writing, no current IEEE standard supports the use of "jumbo frames" (MTU greater than 1500). Although this document contains recommended mechanisms to detect problems in the path, interoperability and reliability of non-standard extensions cannot be assured. Both implementors and users of the protocol described here should exercise caution in its use. 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.
