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 document is a product of the Multiprotocol Label Switching
Working Group of the IETF.

This memo defines an Experimental Protocol for the Internet community.
It does not specify an Internet standard of any kind.  Discussion and
suggestions for improvement are requested.  Distribution of this memo
is unlimited.
