Transparent Interconnection of Lots of Links : MTU Negotiation
RFC 8249, “Transparent Interconnection of Lots of Links : MTU Negotiation”, is a Proposed Standard document published in September 2017 by M. Zhang, X. Zhang, D. Eastlake 3rd, R. Perlman, S. Chatterjee. It updates RFC 6325, RFC 7177, RFC 7780. The canonical text is published by the RFC Editor.
Abstract
The base IETF TRILL (Transparent Interconnection of Lots of Links) protocol has a TRILL campus-wide MTU feature, specified in RFCs 6325 and 7177, that assures that link-state changes can be successfully flooded throughout the campus while being able to take advantage of a campus-wide capability to support jumbo packets. This document specifies recommended updates to that MTU feature to take advantage, for appropriate link-local packets, of link-local MTUs that exceed the TRILL campus MTU. In addition, it specifies an efficient algorithm for local MTU testing. This document updates RFCs 6325, 7177, and 7780.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
