Maximum Transmission Unit Signalling Extensions for the Label Distribution Protocol
RFC 3988, “Maximum Transmission Unit Signalling Extensions for the Label Distribution Protocol”, is an Experimental document published in February 2005 by B. Black, K. Kompella. The canonical text is published by the RFC Editor.
Abstract
Proper functioning of RFC 1191 path Maximum Transmission Unit (MTU) discovery requires that IP routers have knowledge of the MTU for each link to which they are connected. As currently specified, the Label Distribution Protocol (LDP) does not have the ability to signal the MTU for a Label Switched Path (LSP) to the ingress Label Switching Router (LSR). In the absence of this functionality, the MTU for each LSP must be statically configured by network operators or by equivalent off-line mechanisms. This document specifies experimental extensions to LDP in support of LSP MTU discovery. This memo defines an Experimental Protocol for the Internet community.
What “Experimental” means
Describes a specification that is part of a research or development effort, published so the community can gain experience with it.
