This document defines a means for a Label-Switching Router to
verify that its data plane is functioning for certain key Multi-
Protocol Label Switching applications, including unicast
forwarding and traffic engineering tunnels. A new Loopback FEC
type is defined to allow an upstream neighbor to assist in the
testing at very low cost. MPLS Verification Request and MPLS
Verification Reply messages are defined to do the actual probing.
Working Group Summary
Ross Callon has reviewed this for the IESG. It has not been
implemented yet as far as I know.
Note to RFC Editor
Currently the acronym FEC (forwarding equivalence class) is defined
the third time it is used, in the third paragraph of section 1. This
spelling out of the acronym should probably be moved to the first
time that FEC is used (other than the abstract), in the second
paragraph of section 1.
